2.2 PROJECT PROFILE 2.2.1 TYPE OF THE PROJECT
It is a new opencast project.
2.2.2 JUSTIFICATION FOR OPENING OF THE PROJECT:
To meet the increasing demand of power in the country, more and more
super thermal power stations are being planned in western, northern and eastern
India, majority of which are coal based and may be linked from Ib-valley coalfield.
Power Houses of Punjab State Electricity Board, Haryana State Electricity Board
have also been linked to MCL and will be supplied coal from this coalfield. The New
Power houses of TNEB, KPCL, WBPDCL, CESC and DVC are also linked to the
coalfield.
The consumers of MCL are linked to the company and not to any specific
coalfield. The actual supply from any coalfield of MCL will depend upon the
production and transport logistics. Under the above circumstances coalfield wise
demand has been assessed. The projected coal demand on MCL from Ib-valley
coalfield is given below.
Table 2.2 : Projected coal demand on MCL from Ib-valley coalfield (Fig. in Mt)
Sl. No Particulars 2021-22 2026-27
1 Total Demand on MCL 244.83 274.134
2 Projected coal demand on Ib-valley coalfield
97.93 120.56
3 Coal Availability 73.82 85.32
Gap (-)24.11 (-)35.24
From the above table, it can be seen that all the operative mines in the
coalfield along with the new projects will not be able to meet the future demand.
CMPDI
Job No.706135 Chapter – 2, Page - 4
Hence, considering the demand of coal and quarriable potential of the blocks,
formulation of the proposed Basundhara (West) Extension Opencast Project for rated
capacity of 8.75 Mty is justified.
2.2.3 DESCRIPTION OF CORE ZONE
The total land required for mining operations in proposed project i.e. core zone
will be around 323.92 ha involving 227.62 ha of forest land. The core zone of the
project comprising of excavation zone, infrastructure area, safety zone for blasting,
etc., covers partly and/or fully the land from two (2) villages namely,
Gopalpur(Telendih) and Ratansara.
2.2.4 DESCRIPTION OF BUFFER ZONE
The buffer zone i.e. area within 10 km radius from the periphery of the project
boundary.
Basundhara (West) OC, Kulda OC and Garjanbahal OCP are located in buffer
zone.
Basundhara river flows adjacent to mine and Telendra nala is 94 m away.
The reserve forests falling in the buffer zone are Kalatpani RF, Jamkani RF,
Ecologically sensitive areas such as national park, sanctuary, biosphere, etc.
are not present within 10 km radius from the project.
2.2.5 GEOLOGY (PLATE NO. VI, VIA)
"Geological Report on Chaturdhara Block, Ib-River Coalfield," Odisha, was
prepared by CMPDI in March, 1991.
A total of 55 boreholes have been drilled within the area involving a total
meterage of 4196.45m. (Excluding 1 borehole no. HGR - 18 drilled by GSI involving
164.10m.) in an area of 3.57 sq.km. Coal bearing area is 3.57 sq.km out of which
major part is covered by forest. The borehole density/sq.km is about 15.4.

block. It has been intersected in 17 boreholes. Conclusive exposures of Karharbari
formation have not been traced in the area. However, the formation has been
encountered in 7 boreholes. Barakars are well exposed over considerable part of the
block comprising both Rampur and Lajkura group of seams.
Structure
The behaviour of strata is smooth with minor undulations. The strike is roughly
E-W which gradually turns to ESE-WNW in the western part of the block. The dip is
southerly and varies from 6° to 8°. Extreme values of 4° and 11° have, however,
been recorded on the surface along southern bank of Chaturdhara nala in the
eastern and western part of the area respectively.
No positive evidence of any fault anywhere within the block has been observed
either during mapping or in the boreholes. However possibility of occurrence of minor
faults/slips of less than 5 metres throw, cannot be ruled out.

2.4 MINE DETAILS
Mine Boundary Considering the river on its east and nala on the south, mine boundaries
have been fixed and are given below.
North : Incrop of Rampur-I seam.
East : Surface boundary is arrived after leaving 60m surface barrier against Basundhara River and straightening/ smoothening in the south east corner.
South : Surface boundary is fixed after leaving surface barrier of
60m against Chaturdhara nala.
West : Surface boundary is arrived after leaving 7.5m gap from the western block boundary of Chaturdhara block.
Details of Sequence of Coal Seam and Parting
Ib seam is the bottom most seam and occurs in workable thickness range
over a small part only of the block area. It has attained workable thickness only in two
boreholes located in eastern part of the block.
Lajkura seam occurs at the top and is incroping on the dipside edge of the
block and has not been studied in detail because of its restricted occurrence within
60m barrier zone of the Chaturdhara nala. It incrops over a small zone of the quarry’s
southern boundary and thereby not considered.
Rampur seam underlying Lajkura seam and overlying Ib seam occurs in six
splits and is considered the only workable seams for the proposed project. The
seams in ascending order are RAMPUR-I, RAMPUR-II, RAMPUR-III, RAMPUR-IVB,
RAMPUR-IV and RAMPUR-V.
CMPDI

It has been observed that the maximum incremental value of PM10 was found
at Telendih (core zone) as 29.61 µg/m3 without control measures and 21.59 µg/m3
with control measures. The absolute values of PM10 at Telendih village with control
measures is observed as 120.01 µg/m3 which is well within the permissible limit of
250 µg/m3 as per coal mine standards.
In buffer zone also at all eight stations the value of PM10 and PM2.5 has been
observed well within permissible limit of NAAQS 2009 except value of PM10 at
Ghogharpali village. To further bring down the value of PM10 at Ghogharpali village,
additional control measures (eg. Fog canon) will be deployed. Apart from this three
tier green belt will also be developed at down wind direction to arrest the particulate
matter.

4.2 ASSESSMENT OF IMPACT AND CONTROL MEASURES ON
HYDROLOGY & HYDRO-GEOLOGY
The adverse impacts are changes in ground water flow patterns, lowering of
water table, changes in the hydrodynamic conditions of river/underground recharge
basins, reduction in volumes of subsurface discharge to water bodies / rivers,
disruption & diversion of water courses / drainages, contamination of water bodies,
affecting the yield of water from bore wells and dug-wells, etc.
Knowledge of mining impact on ground water is requisite while deciding and
designing to protect surface water bodies. Predicted mining impact on water is
broadly classified as:
4.2.1 QUANTITATIVE IMPACT & CONTROL MEASURES ON WATER
4.2.1.1 PROPOSED CONTROL MEASURES FOR DISRUPTION OF NATURAL
DRAINAGE NETWORK LOCATED IN THE CORE ZONE
The drainage system of the area will be undisturbed as there is no proposed
nallah diversion.
4.2.1.2 PROPOSED CONTROL MEASURES TO PROTECT SURFACE WATER BODIES FROM SILTATION AND CHOKING OF WATER COURSES RESULTING IN SCARCITY OF SURFACE WATER AND FLOODING PROBLEM IN THE AREA
The drainage arrangement for smooth disposal of storm water from external
overburden dump is extremely essential to avoid gully formation on the dump body
and also siltation problem of the nearby natural drains. The following steps will be
followed for effective drainage:
CMPDI
Job No.706135 Chapter – 4, Page - 6
Drainage arrangement for External OB Dumps
Catch drain
An open drain of appropriate size will be provided on all terraces at the foot
of next bench to receive the storm water from upper benches. This will be then
discharged to the lower benches through masonry chute, thus minimizing gully
formation in the slope of external dump.
Foot drain
A foot drain of proper size will be provided around the external OB dump
(portion exposed to outside only). This drain will collect run-off from dump and direct
it to settling tank/sedimentation pond before discharge to nearby natural water
courses.
Drainage arrangement for Internal OB dumps
A part of the quarry will be backfilled with overburden. The backfilling will be
carried out in a phased manner. Once the backfilling has reached a certain
predetermined reduced level, the plots will be leveled graded and cleared of large
stone pieces lying on the surface. The slope of the ground will be made very gentle
as far as possible (preferably less than 2%). The graded and leveled area will be
divided into small sectors and small check bunds will be constructed to retain
moisture and humus in the soil. The drainage arrangements for precipitation run-off
are as follows:
During working stage, the run-off will be collected from internal dump by
foot drain for diverting to mine sump for pumping.
In the post-mining period, the drainage pattern of the reclaimed area
will be such that the run-off will be diverted to final void of the quarry as
a measure for water harvesting.
CMPDI
Job No.706135 Chapter – 4, Page - 7
4.2.1.3 PROPOSED CONTROL MEASURES TO PROTECT SURFACE WATER
BODIES FROM REDUCTION AND CHANGES IN STORM RUN-OFF OR
SURFACE RUN-OFF WATER COURSES
When the opencast mine is commissioned, garland drain will be provided
around the excavation boundary to guard against mine inundation due to rainfall run-
off or storm run-off. Mine water generated from excavation area by direct rainfall will
be pumped time to time for safe mine operation after meeting the internal
requirement.
4.2.1.4 PROPOSED CONTROL MEASURES TO PROTECT DECLINING OF
GROUND WATER LEVEL FROM EARLY DRYING UP OF SURFACE
WATER BODIES LIKE PONDS, LAKES & STREAM FLOW
There is an intricate relationship between surface water and ground water. In
the monsoon time, till the aquifer attains its original ground water level, the surface
water bodies like stream flow, ponds & lakes recharge the aquifer. As soon as the
ground water recoups and attains its level, the groundwater contributes water to the
surface water bodies. After post-monsoon period, this process is reversed again as
the ground water level gets lowered from the original level. This recharge and
discharge system of the area brings surface water and ground water relationship
complicated. The water balance studies of this area unties the above said intricate
relationship of surface and ground water.
Considering the hydrogeological set-up of the area, the estimated radius of
influence from the available hydrogeological parameter will be 57 mts due to mine
dewatering. This mine dewatering would bring down the ground water level in the
immediate vicinity of the mine. Maximum effort will be made to recycle or reuse the
treated effluents totally to the extent possible by keeping the makeup water in
different sumps or lower bench of the mine as a measure for ‘rain water harvesting’
in the project. In unusual situations during monsoon, mine discharge water will be
allowed to go as recharge/run-off in the same basin of the area. The backfilling
operation of mining will restore water level in the immediate vicinity of the excavation
area by arresting mine seepage.

4.2.2 QUALITATIVE IMPACT ON WATER
Mining and its related activities create water quality problems. These
problems are identified and the likely sources of water pollution from this project
(c) Waste water from mine -- Suspended solids of coal, clay and oil.
(d) Surface run-off passing through coal stockpiles -- Suspended solids
(e) Storm water from leasehold area and built-up area -- Suspended solids.
4.2.2.1 EFFECTIVE WATER POLLUTION CONTROL MEASURES ON QUALITY
ARE TAKEN/SHALL BE CONTINUED AT THE PROPOSED MINE
KEEPING THE FOLLOWING POINTS IN VIEW
Sufficient safeguards during the planning stage to make the project eco-
friendly from water pollution control point of view.
Recycling of wastewater after appropriate treatment to achieve "zero
discharge" to the extent possible at some sources.
Conforming to the limits of the Environment (Protection) Amendment
Rules, 2000 (“Schedules-VI”, General Standards for discharge of
environmental pollutants, Part-A : Effluents) for quality of the treated
effluent.
4.2.2.2 SANITARY (DOMESTIC) WASTE WATER
About 80% of the total consumption will contribute to sanitary waste water
which will be treated mainly for total suspended solids (TSS) and bio-chemical
oxygen demand (BOD). Therefore, depending upon the pollution load in the domestic
effluent, a suitable treatment scheme with sedimentation tank for TSS and aeration
facilities for BOD will be formulated out (Fig.-4.1) and commissioned for the project
as and when needed. Treated water will be utilized for watering the plants. Sewage
Treatment Plant (STP) will be provided for domestic waste. Water balance flow-chart
is given in Figure 4.1

4.2.2.4 WASTE WATER FROM MINE
Mine discharge water will be collected in a sump pit located in the mine floor
from where it will be pumped out and diverted to mine discharge treatment plant
(MDTP) consisting of oil and grease trap and sedimentation pond(s) with chemical
dozing arrangement to arrest suspended solids and oil and grease. Then, treated
water will be used for dust suppression in haul road and CHP besides washing of
dumpers and/or dozers in workshop. The sludge collected from the pond(s) will be
utilized as landfill in the decoaled area. The oily sludge from oil and grease trap(s)
will be disposed off in the impervious layer lined pit. Oil and grease recovered
manually from the trap(s) will be stored in drums safely for disposal through auction.
Effort will be made to keep the balance make up water in the lower benches of the
mine as a measure for “Rain Water Harvesting”. In unusual situations during
monsoon, mine discharge will be allowed to go as recharge / run-off in the same
basin of the area.

4.2.2.5 SURFACE RUN-OFF
(a) From OB dumps
The surface run-off from the OB dump will be collected in garland drain of
appropriate size provided at the foot. The foot drain will carry water to a
sedimentation pond from where the overflow would be directed into natural drain
through controlled discharge outlets. The overflow will be monitored regularly for TSS
to enable corrective actions before water meets the natural water ways.
(b) From coal dumps
Drains will be provided around the coal dumps to collect run-off for diverting
into sedimentation ponds before discharge into natural water courses.
4.2.2.6 STORM WATER
To prevent inrush of precipitation run-off from the outside area to the quarry,
storm water drains of suitable dimensions will be provided at appropriate locations
with outlets to natural water courses. Settling tanks/ponds will be provided in the
storm water drains at convenient locations to take care of suspended solids.
4.2.2.7 MEASURES FOR GROUNDWATER RECHARGING
The decoaled voids will be used for water harvesting structures.
The backfilling will arrest the mine seepage resulting restoration of
ground water in the immediate vicinity of the area.
The unlined garland drain and sedimentation pond will enhance the run-
off recharge.
Further, sufficient available rainfall recharge of aquifers will supplement
the restoration of ground water regime of the surrounding area.

Seepage from strata and surrounding, etc. 1.09
The waste water from mine will be collected in a sump pit located in the mine
floor from where it will be pumped out and diverted to a sedimentation pond to arrest
suspended solids. Then, the clear water will be recycled for industrial use, fire
fighting, watering of plants and dust suppression in haul road besides washing of
dumpers or dozer in workshop. The pumping of mine water during mining in
Basundhara West Extn. OCP will not adversely affect the ground water regime in the
CMPDI
Job No.706135 Chapter – 4, Page - 21
surrounding area due to availability of sufficient replenishable annual ground water
recharge in the area. As a matter of fact, the mine make-up water will be conserved
in the lower benches as a step for rain water harvesting to meet project water
requirement.
4.2.7 CONCLUSION
The following conclusion is drawn from the above study:
Mining operation will create voids or depressions, which are inducing or
accelerating rainfall recharge and run-off in the mining area.
After considering mine discharge, domestic as well as cultivation
requirements, the balance annual groundwater recharge comes to
about 39.47 Mm3/annum.
Maximum effort will be made to recycle or reuse the treated effluents
totally to the extent possible by keeping the make-up of water in different
sumps or low lying area of the project.
4.3 NOISE QUALITY
4.3.1 NOISE IMPACT ASSESSMENT
The major adverse impacts during pre-mining and mining phases are
generation of obnoxious levels of noise & vibrations which also spread in
neighbouring communities.
The other impacts are occupational health hazards, damage to structures,
disruption in wildlife, etc.
NOISE PRODUCING SOURCES
The sources of noise will be:
Drilling operation in OB
Blasting for overburden
Operation of HEMMs
Operation of equipment in CHP, workshop, etc.
CMPDI
Job No.706135 Chapter – 4, Page - 22
The noise associated with mining activities may be classified into three types:
Continuous
Intermittent
Impulse
IMPACT OF NOISE
The workmen associated with the operation of HEMMs, etc. will
experience a noise level above stipulated 90 dB (A) [DGMS Circular, No.18
(Tech.) of 1975] for more than 4-4.5 hours per shift. Unless suitable
mitigatory measures are taken, high noise pollution will have impact on the
workmen. It is worthwhile to mention that intermittent and impulse noises are
considered to be less dangerous than continuous noise due to the short
exposure duration except under the situation when the level exceeds 115 dB
(A).
4.3.2 NOISE POLLUTION CONTROL MEASURES
The following control measures shall be taken:
Proper designing of plant & machinery by providing in-built mechanisms
like silencers, mufflers and enclosures for noise generating parts and
shock absorbing pads at the foundation of vibrating equipment.
Routine maintenance of equipment.
Rational deployment of noise generating plant and machinery.
Greenbelts around the quarry, infrastructure sites, service building area
and township besides avenue plantation on both sides of the roads to
maintain noise level at night time within the limit for the inhabited
localities situated at a very close proximity.
Locating township away from noise centre.
HEMMs with sound proof cabins.
Provision of isolation for vibrating equipment (both fixed and mobile)
foundation.
CMPDI
Job No.706135 Chapter – 4, Page - 23
Personal protective devices to all the persons working in high noise
areas.
Regular monitoring of noise levels at various points.
4.4 RISKS AND HAZARDS
Risks and hazards arise mainly from blasting and mine occupational activities
and are well established.
4.4.1 IMPACT ON BLASTING VIBRATION
Blasting may affect the mineworkers as well as people residing in the vicinity
of mine and dependent upon the type & quantity of explosives used pit geology,
topography and confinement of the blast.
Measures for safe blasting
Due attention will be given to the following factors:
(a) All provisions of Coal Mines Regulations will be followed.
(b) Overcharging will be avoided and quantity of explosive will be decided
as per conditions imposed by DGMS.
(c) Stemming material to be used is sand. However, the drill cuttings and
chips of triangular shape can be used as an effective stemming material
with proper packing.
(d) Use of millisecond delay detonators that are initiated by shock tube
initiation system, between rows and between holes in the same row.
(e) Blasting will be done in day time during the shift change over period as
per requirement. However, the frequency of blasting will depend upon
the availability of land (tenancy in particular), DGMS permission for use
CMPDI
Job No.706135 Chapter – 4, Page - 24
of explosive, meteorological condition, geo-mining condition and
method of mining.
(f) Before blasting is done, warning sound is given so that people can
move to safe places.
4.4.2 BLASTING AND VIBRATION CONTROL MEASURES
Proper conformation to measures for safe blasting as mentioned above,
to avoid damage to any structure or annoyance to the people in the
colony area or neighbouring villages.
Proper design factor will be taken while constructing various structures
for stability against vibration.
A blasting danger zone will be kept around the periphery of the quarry.
This zone will be kept free from village habitation and community
infrastructure and thus impact of vibration after blasting on the surface
structures is avoided.
Controlled blasting will be done near built-up areas and surface
features, as and when required.
Adoption of present day technology of use of site mixed slurry (SMS)
explosives.
4.5 IMPACT ON SOCIO ECONOMIC PROFILE
The major adverse impact is the displacement and rehabilitation /
resettlement of affected people including change in culture, heritage & related
features. The crime and illicit activities also prop-up due to sudden economic
development of the area.
POSITIVE IMPACTS:
The project is likely to give a boost to the economy of the area and providing
primary and secondary sectors employment to local people.

Areas to be covered under the CSR activities:
1. Supply of water for drinking and domestic use in the nearby villages.
2. Education facility is to be enhanced in the area to improve the education level
of the villagers. It is also needed that a facilitator in the school may also
improve the quality of teaching and will be interactive and participatory.
3. Medical facilities in the area is to be enhanced so that symptoms of illness
may be reduced.
4. It is required to work on the cleanliness and toilet construction in the area as
open defecation is prevalent in the area.
5. There is need to develop places for community use like community centres,

7. It is also needed that to do forward linkage of the finished goods of the nearby
areas.
4.6 IMPACT ON BIO-DIVERSITY
Environmental impact assessment (EIA) is the formal process used to predict
the environmental consequences (positive or negative) of a plan, policy, program or
project prior to the decision to move forward with the proposed action.
Possible Impacts
The major adverse impacts due to pre-mining and mining phases are loss of
habitat, biodiversity, flora & fauna, fisheries & other aquatic life, migration of wildlife
and overall disruption of the ecology of the area. Due to mining activity, the land use
will undergo progressive changes involving quarrying, transportation etc. The physical
and / or biological reclaimed land would undergo transformation over time which would
have positive impact on environment.
As per Simpsons biodiversity index, the Core zone values ranged between
0.33 - 0.72, which is lower than buffer zone forest 0.72 - 0.80. This suggests that there
are more species in the buffer zone of the study area. The values calculated through
this index reflects the good biodiversity in the study area as a whole. Therefore, due to
mining activities, there would be direct as well as indirect impact on ecology and
biodiversity. The Project Proponent therefore needs to provide adequate measures for
minimizing the impact on biodiversity and also carry out extensive plantation and
afforestation in an open areas for creating and augmenting natural resources.
It is found that both core and buffer zones are found to be free from
endangered / endemic species of Flora and Fauna, migratory species of Fauna,
migratory corridors, breeding and spawning grounds are not present within the survey
area of the project. However, the buffer zone has several patches of natural forest
CMPDI
Job No.706135 Chapter – 4, Page - 29
which needs to be conserved and extensive afforestation plan is recommended for
augmenting natural resources.
In the area mining activities are going on. The population of fauna, especially
mammals is found to be low. So there will be no adverse impact on the fauna existing
in the project impact zone.
4.6.1 IMPACT ON FLORA
The core zone vegetation is partially natural, remaining are agricultural lands
predominantly paddy cultivated. The wild vegetation is denuded by the neighbouring
villagers. Only few sporadic trees (Mahua, tendu, kadam, neem, mango) present.
Invaded shrubs like Chromolaena, wild sponge guard, are frequently present. The
buffer zone vegetation contains some patches of Sal forest, agriculture lands and a
small hill range forest. The natural ecosystem will be disturbed in the core zone area
because of the mining project. When the project is started, the people living in the
core zone area will start using the bio resources of the buffer zone area, which leads
some impact on the natural ecosystem of the buffer zone.
4.6.2 IMPACT ON FAUNA
The Project area comes under IB valley Coalfield, where mining activities are
prevalent since last many years. There were no major faunal habitats in the proposed
mining area. During survey, it was observed that endangered, endemic and migratory
species were not present in the study area. Also, migratory corridors, flight paths and
spawning grounds were not present in the study area. However, Post mining phase it
is suggested to reclaim the mine spoil area through adequate technical & biological
reclamation methods, so that the vegetation will support habitat development for
various types of faunal species.
4.6.3 CONTROL MEASURES
4.6.3.1 CONTROL MEASURES TO REDUCE THE IMPACT ON FLORA
The enhancement of forest area occurs due to measures like biological
reclamation of backfilled area, arboriculture / afforestation,
compensatory afforestation creation of greenbelt and avenue plantation.
CMPDI
Job No.706135 Chapter – 4, Page - 30
Water body created by the final voids is beneficial to flora as the area is
prone to water scarcity.
This project will have no detrimental impact on diversity of floral species
within terrestrial and aquatic habitats.
4.6.3.2 CONTROL MEASURES TO REDUCE IMPACT ON FAUNA
The balance in the regional population will be maintained in natural
course, owing to existing undisturbed forest areas in the vicinity of the
project. The increase in green cover due to implementation of various
measures like biological reclamation of backfilled area, arboriculture /
afforestation adopted by the mine establishment will be an added
bonus, though expected in distant future.
The mine will be a “zero-discharge” one. If required, water is
discharged only after suitable treatment. No adverse impact on
downstream aquatic life of surface water courses is expected.
The project is not likely to have impact on the faunal species diversity
within the terrestrial and aquatic habitats.
4.6.4 SPECIES COMPOSITION FOR GREEN BELT DEVELOPMENT
Creation of a greenbelt with local species will enhance the project
area. The greenbelt should be developed around the quarry,
infrastructure sites, service building area and township besides
avenue plantation on both sides of the roads.
The purpose of a green belt around the mining site is to capture the
fugitive emissions, attenuate the noise generated and improve
aesthetics. Green vegetation cover is beneficial in many ways in
terms of conservation of biodiversity, retention of soil moisture,
recharge of ground water and maintaining pleasant micro climate of
the region. In addition, vegetation cover can also absorb pollutants
from the environment and helps in effective pollution control.
CMPDI
Job No.706135 Chapter – 4, Page - 31
The mix of species suggested for green belt development are
presented below in table 4.8. This may be taken up after due
consultation with concerned forest division.
Table 4.8: List of Plants recommended for green belt development/ land
reclamation
Common Name Family Name Botanical Name
Babool Leguminosae Acacia nilotica (L.) Willd ex Delile
Australian black wattle Leguminosae Acacia auriculiformis A.Cunn ex Benth.
Where any permanent building or structure of permanent nature not belonging
to mine owner lie within the danger zone, the aggregate maximum charge per delay
and per round shall not exceed the amount fixed by DGMS on the basis of a scientific
study.
7.1.6 EXPLOSIVE HANDLING
The present day technology of blasting with site mixed slurry/emulsion
(SMS/SME) explosive shall be used with milli second delay detonators that are
initiated by shock tube initiation system. SMS/SME is stored by the supplier as per
GOI Notification. Further, transport and charging are also done by the supplier on
the spot. Only priming will be done by the project authority.
CMPDI
Job No.706135 Chapter – 7, Page - 6
For storage of explosives meant for priming, detonating fuse and detonators,
one service magazine has been provided.
7.1.7 SAFETY RULES
Mining operations follow statutory mine safety rules administered by the
Directorate General of Mine Safety (DGMS), Chief Controller of Explosives and
others. Planning and design of electrical installations will take into account the
existing electricity rules to obviate the hazards due to use of electricity.
For creating safety awareness and imparting education on safe practices, the
following steps shall be taken:
Holding annual safety weeks.
Imparting basic and refresher training to new and old employees
respectively as per Vocational Training Rules.
7.1.8 MINE INUNDATION
Due care has been taken while formulating the PR to prevent water ingress
during mining operations from the higher ground local rivers/reservoir.
Embankment is not required because HFL against Basundhara river is 259 m
above the mean sea level. Surface of the quarry is more than 10 m above the HFL.
7.1.9 FIRE AND SPONTANEOUS HEATING
The most vulnerable points for fire in an opencast mine is in the Coal stock,
old coal benches with loose coal, HEMMs, OB dumps with carbonaceous shales etc.
The common accidents due to fire may take place while working or deploying shovels
in a fiery seam where there are chances of fall of sides forming thick cloud of hot dust
and injuring the personnel nearby. Accident due to fire may take place while dealing
with fire in coal stocks, old coal bench with fire etc. The following precautions may be
taken to deal with fire in OCPs.
CMPDI
Job No.706135 Chapter – 7, Page - 7
i) In order to prevent accidents due to fire every mine should have a
proper firefighting organization under the control of Manager of the mine
or the Safety officer. Firefighting stations should be established near the
entrance of the mine with adequate firefighting equipment.
ii) Adequate number of persons should be trained in firefighting who
should be familiar with all firefighting equipment.
iii) The coal stocks should be regularly liquidated or else it should be
properly dozed and made dome shaped to prevent entry of air and

7.6 RAIN WATER HARVESTING
Rain water is naturally pure water except where it becomes acidic due to
industrial pollution. The rapid exploitation of ground water as well as surface water
due to the industrial developmental projects, increase in population resulted in acute
scarcity of fresh water availability. It has become necessary to conserve this
valuable natural resource for sustainable development.
Conservation of this valuable natural resource can be done by collecting this
rain water scientifically and utilizing it either for drinking purposes or ground water
recharging purposes.

7.7 SLOPE STABILITY
7.7.1 Slope
Any structure either naturally occurred or artificially built when takes the
shape by increasing the height with horizon in reference to plane is called slope.
Slopes of the earth are of two types
1. Natural slopes
2. Artificial slopes
Natural slopes are those that exist in natures and are formed by natural
causes and generally exist in hilly area.
Artificial slopes are created by man such as cutting of sides, construction of
dam, highway embankment, mining benches and OB dumps, etc.
CMPDI
Job No.706135 Chapter – 7, Page - 16
7.7.2 Factors governing the Slope Stability
There are two main aspects of slope failure and they are natural and man
made disturbances. The seismic activities of the earth crust, rain, tornado and
geology come under the naturally occurred disturbance. The blasting, excavation,
dumping are the man made disturbance for slope instability. Following are the main
factors that influence the slope stability.
7.7.2.1 Geo physical parameters
(a) Shear strength parameters:-
This is the basic parameters and holds the key role to control the
stability of the slope but it is most difficult to comprehend it accurately.
The fundamental shear strength equation proposed by French engineer
Coulomb is S=C + б Tan (Φ).
(b) Bulk density of dump mass:
Bulk density of dump mass determines the weight of waste rock and ply
very important role in calculation of stability of the dump mass
(c) Base of the Dump
Base of the OB dump should be strong enough to bear the load of the
dump otherwise base failure may crop up.
(d) Grain size distribution of the dump material:
It indicates composition of dump material comprising of clay, silt, sand,
gravels and boulders. It influences the permeability, density, shear strength
parameters and other characteristics of the soil materials.
(e) Plastic Limits
Atterberg limits determine the expansive and liquid properties of the
material. In case of expansive soil, shear strength properties drastically
changes when coming in contact with water.
CMPDI
Job No.706135 Chapter – 7, Page - 17
(f) Co-efficient of permeability:
This parameter implies seepage properties of water and facilitate in
computation of seepage force exerting on dump materials.
7.7.2.2 Geology of the Area:-
Geological features that could pose problems to site stability and that
therefore warrant detailed site studies prior to development within the area include:
type of strata, erosion, sheared mélange matrix, hydrothermally altered rock,

The total ML area of this project is 323.92 ha, out of which 192.40 ha will be
biologically reclaimed.
Major part of the quarry will be backfilled with overburden. The backfilling will
be carried out in a phased manner. Once the backfilling has reached a certain
predetermined reduced level, the plots will be levelled, graded and cleared of large
stone pieces lying on the surface. The slope of the ground will be made very gentle
as far as possible (preferably less than 2%). The graded and levelled area will be
divided into small sectors and small check bunds will be constructed to retain
moisture and humus in the soil. The outer slope of each bench will be kept at the
natural angle of repose of the spoil material and at overall slope angle of 28O
considering all benches.

10.1.9.6 MANAGEMENT OF TOPSOIL
Topsoil is the top portion of the soil cover ranging in depth from 50-350 mm.
It is the dark coloured (though it may not be true always due to the influence of parent
rock), rich in active and decomposed organic material mixed with fine mineral
particles with only small agglomoration. The nature takes above 100 years or more to
build about 25mm of top soil.
10.1.9.6.1 Constituents of Topsoil:
It is the zone of eluviation which represents the top soil and easily
distinguished physically from other horizon by its colour, texture and a thick
accumulation of organic vegetative matter. In case of Intrazonal and Azonal soils, A-
Horizon is not distinct although these soils possess topsoil. The constituents of top
soil are:
i) Plant Leaves and debris.
ii) Semi-Decomposed and decomposed organic material (humus) solution
of organic and carbonic acids.
iii) Inorganic elements like Nirogen, Phosphorus, Potasium, Magnesium,
Boron, Sulphur, Iron, Copper etc.
iv) Micro-Organisms like microscopic bacteriam Fungi, Protozoa,
earthworms etc.
CMPDI
Job No.706135 Chapter – 10, Page - 12
10.1.9.6.2 Formation of Topsoil
The biotic factors or Biological processes play the Vital role in the formation
of Top soil. The factors responsible for the formation are:
i) Vegetation: The fallen leaves and the decayed vegetation contribute
directly in the formation of himus. Further plants helpto maintain fertility
by bringing inorganic minerals from the lower layers.
ii) Micro-organisms: The microscopic bacteria , fungi, protozoa etc help
directly in converting plants and animal remains into humus. Again
these organisms become a part of the humus after death. Some
microbacteria transforms atmospheric nitrogen into Nitrates and
increase the Fertility.
iii) Animals: The excreta of the burrowing type animals helps in the
development of the topsoil. The ants and termites bring the soil from
lower horizon to the surface. Similarly the earthworms contribute in
mixing the organic renains with the minerals and then bring them to the
surface.
10.1.9.6.3 Formation of Topsoil: Why preservation and Reuse of Topsoil?
Biological activity is a good indicator of the health of topsoil. To maintain
maximum level of this activity, its preservation is highly essential. The topsoil is
physically well textured , chemically highly fertile and biologically hughly active. The
reuse of it is suggested due to following:
i) Humus yields organic acids which assist soil solution.
ii) It produces plant food i.e. Phosphorous, Calcium, Potassium, Nitrogen
etc.
iii) It retain soil moisture besides providing the desired arrangement of soil
structure favourably for plant growth.
10.1.9.6.4 General depth of soil in :
Its depth depends on following:
i) Physiography.
CMPDI
Job No.706135 Chapter – 10, Page - 13
ii) Climatic conditions like temperature, rainfall etc.
iii) The uses to which the land has been put before.
In a mining block it is necessary to have a close soil survey to determine its
depth. From the soil analysis available the approaximate depth of the topsoil of
various mining blocks of Ib Coalfield is given below:
Name of the Block

Topsoil texture Rematk
Kulda 200-250 Sandy/Sandy Loam The depth varies from location to location in an area and to be determined at specific site before stripping,
Basundhara 250-300 Sandy Loam/ Loam
10.1.9.6.5 Storage and preservation of topsoil:
Topsoil undergo many changes during preservation. These are:
(A) Changes in topsoil due to storage.
i) Stockpiling has profound affects on the physicochemical and biological
properties.
ii) Biological activity diteriorates after 3 to 6 months of storage.
iii) Stockpiling reduces organic content and affects the organic compound
concerned in soil aggravation.
iv) Aggregate stability is reduced to some extent due to storage.
iv) Following three zones are developed in the topsoil mound during
storage:
Aerobic zones: Soil is active in this zone
Transition zone: Fluctuates between predominantly aerobic and
anaerobic status.
This zone is inactive and low in buological activity as well as
organic content.
(B) Methology of Stripping: The method of stripping should be normally by
the scrappers only. The routing of scrappers during this operation must
be planned to mininmise the travel of machines to avoid compaction
and damage of soil structure. Furtherm careful control of operation is
CMPDI
Job No.706135 Chapter – 10, Page - 14
necessary to ensure planned stripping depths of the topsoil and sub-
soil. These soils should be stripped and stored separately. Intermingling
of these soils during stripping is not a good practice.
(C) It is essential that topsoil stripping is carried out when it is as dry as
possible to reduce the risk of compaction and damage to the soil
structure by smearing and remoulding. Prolonged rainfall is unsuitable.
The best part of the year is when evapo-transportation exceeds
precipitation i.e during the months of March-September.
(D) Geometry of Topsoil Heap: The heap should be constructed to facilitate
the following:
To provide the maximum surface area for mantaining greater level
of Biological activity.
To have slopes capable of sustaining vegetation to avoid erosion
and gully formation.
Space constraints imposed by the site factors and soil texture would
generally dictate the overll size and shape of the heap. As a rule of the
thumb, the following stack geometry may be mantained as far as possible to
preserve the topsoil and increase the shelf life.
a) Height:
i) 4.0m (Max) for sand soil
ii) 2.0 to 3.0 for loamy soil
iii) 1.0 for heavy clayey soil
iv) 0.5 to 1.0 for intermediate soil texture.
b) Slope:
Wide slope of 1 in 3 (i.e 18.50 to the horizontal)
If there is constraint in the availability od area, one or both pof the
following strategies can be adopted:
CMPDI
Job No.706135 Chapter – 10, Page - 15
ALT-I
An acoustic barrier of topsoil may be constructed in the safety zone
near the working face. When the working face advances , the embankment
away from it may be reclaimed and respread over the subsoil of the
technically reclaimed area. This would abate the noise pollution besides
noise preservation of topsoil and reduction of thr demand on the land
requirement.
ALT-II
Intial topsoil may be spread over the area to be mined. When the scope
for progressive reclaimation is available, the respread topsoil along with the
insitu one may be stripped carefully and utilised. This method would also
preserve the topsoil and reduce the demand on landintake.
E) It is advisable to avoi the topsoil storage, specifically the longterm one.
However if storage is unavoidable upon completion of the surface of the
heap, the following steps are to be followed to keep the soil in good
health and to increase its shelf life.
a) Surface ripping with suitable sub-soiling machine for the purpose of
aeration and relieving surface compaction.
b) Immediate cultivation of suitable low maintanance species like dwarf
grasses to prevent erosion and guily formation.
c) Maintenance of surface vegetation actively by seeding, mowing, and
weed control operation.
10.1.9.6.6 Topsoil Carpeting
The following golden rules need to be observed:
i) Overburden, sub-soil and topsoil should be respread to correct
sequence putting the topsoil on the top of the back filled area.
ii) Top soil should be respread over the restoration area at an even depth
so as to achieve the final level and suitable configuration for drainage.
iii) As far as possible progressive top soil reclaimation technique should be
practised. The topsoil from the area lying just ahead of the advancing
CMPDI
Job No.706135 Chapter – 10, Page - 16
opencast mine edge should be scrapped off by scrapper and
immediately placed over the technically reclaimed area.
iv) Compaction of topsoil after respreading over reclaimed area should be
avoided by properly planning the movement of Earth Moving Machinery
and carrying ou the operation in dry period only.
v) If topsoil is to be reclaimed from the heap for spread in the backfilled
area and OB dump area, the reclaimation should be planned in such a
wat that materials from aerobic , transition and anaerobic zones are
takem simultaneously. The above zones should not be taken out
separately as it is essntial to use the active surface layer as ‘inoculum’
during soil respreading to recover the inactive portion of the mound as
quickly as possible.
10.1.9.7 MANAGEMENT / DECOMMISSIONING OF INFRASTRUCTURE
The infrastructure like workshop, office buildings, residential colony, roads
and transmission lines, etc., will be provided for the project. Considering the ground
realities existing during the period just one year before mine closure, plan for
reutilization in neighbouring mines or decommissioning will be made. If
decommissioning of infrastructure is done, the land occupied by the infrastructure will
be restored for some useful purpose. The cost for decommissioning will be met from
the 'Fund' created for mine closure activities.
10.1.9.8 MANAGEMENT OF DISPOSAL OF MINING MACHINERY The salvaging and shifting operation of mining machinery and other
equipment will be planned considering the ground realities existing during the period
1 year advance of final closure of the mine.

In the post-mining period, the drainage pattern of the reclaimed
area will be such that the run-off will be diverted to final void of the
quarry which will be developed as a water reservoir for water
harvesting and also recharging the aquifer in the surrounding
area.
There is an intricate relationship between surface water and ground
water. In the monsoon period, till the aquifer attains its original ground water level,
surface water bodies like stream, ponds & lakes recharge the aquifer. As soon as
ground water recoups and attains its level, it contributes again to surface water
bodies. After post-monsoon period, this process is reversed again as ground water
level gets lowered from the original level.
The mine dewatering brings down ground water level in the immediate
vicinity of the mine. Maximum effort will be made to recycle or reuse the treated mine
discharge water totally to the extent possible by keeping the make up water in
different sumps or low lying areas of the project. In unusual situations during
monsoon, mine discharge water will be allowed to go as recharge/run-off in the same
basin of the area.
As such, this area is having an average annual rainfall of 1514 mm.
This rainfall replenishes the annual ground water draft every year. This will enhance
the recharge of the aquifer in the area for mitigating the lowering of ground water
level in the area surrounding the mine.

11.2 DESCRIPTION OF THE ENVIRONMENT
To assess the existing environmental scenario, baseline data has been
generated for various environmental components (such as air, water &noise) by
M/s Ecomen Laboratories Pvt. Ltd. during the period 4th November 2017 to 3rd
February 2018. The flora fauna & Socio-Economic study was done by M/s. VRDS
Consultants. The detailed report is given in EIA/ EMP.
For baseline data of ambient air quality, Nine (9) monitoring stations (1 in
Core zone & 8 in Buffer zone) were fixed on the basis of meterological parameters
like predominant wind direction and wind speeds besides physiography of the
area. Twenty four (24) hourly data have been generated for each parameter i.e.
PM10, PM2.5, SO2 and NOX at each monitoring station for two days in a week for
four consecutive weeks in a month for three months i.e. 4th November 2017 to 3rd
February 2018. The average concentration levels (24 hrly) of all parameters for all
buffer zone stations are well within the permissible limit of the National Ambient Air
Quality Standards (NAAQS) 2009.
The baseline data w.r.t water quality of various inland surface water and
ground water sources had been generated. Nine (9) sampling stations covering
surface water, ground water and mine water discharge were selected in the core
zone and buffer zone of the project. The analysis shows that various physical and
chemical parameters are within permissible limit.
The ambient noise level (leq) measurement for the project covering both
core zone and buffer zone stations (9 stations) are within the permissible limits.
The flora & fauna study was conducted during November 2017 to January 2018 by
M/s. VRDS Consultants.

11.3 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
There will be impacts on different environmental components e.g. air,
water, noise, flora & fauna, land etc. due to mining and its related activities which
are described below:
11.3.1 Impact on air quality & control measures
Ambient air quality will be affected due to presence of PM10 PM2.5, SO2&
NOX which will begenerated due to various activities related to project. To predict
the impact on the air quality, Air Quality Impact Predict was done using
AERMOD software.
It has been observed that the maximum incremental value of PM10 was
found at Telendih (core zone) as 29.61 µg/m3 without control measures and
21.59 µg/m3 with control measures. The absolute values of PM10 at Telendih
CMPDI
Job No.706135 Chapter 11, Page - 7
village with control measures is observed as 120.01 µg/m3 which is well within
the permissible limit of 250 µg/m3 as per coal mine standards.
In buffer zone also at all eight stations the value of PM10 and PM2.5 has
been observed well within permissible limit of NAAQS 2009 except value of PM10
at Ghogharpali village. To further bring down the value of PM10 at Ghogharpali
village additional control measures (eg. Fog canon) will be deployed. Apart from
this three tier green belt will also be developed at down wind direction to arrest
the particulate matter.
Appropriate air control measures will be adopted to maintain the ambient
air quality within the stipulated standard. The control measures which will be
adopted are as follows:
All drills are/will be equipped with dust extractors and wet drilling is
recommended in all drilling operation.

safe places.
A blasting danger zone will be kept around the periphery of the quarry. This
zone will be kept free from village habitation and community infrastructure.
11.3.4 Impact on land resource & control measures
The major direct impacts on existing land use during the pre-mining
phase are the removal of vegetation and resettlement of displaced population.
There may also be land use changes with respect to agriculture, fisheries,
CMPDI
Job No.706135 Chapter 11, Page - 9
recreation sites, housing, forestry areas, etc. Land reclamation / restoration of
mined out lands may give rise to enhanced beneficial land use.
Control measures
In proposed project there is no external dumping. All the OBs will be dumped
internally.
During pre-mining the total forest land involved in the project is 227.62 Ha,
however at the time of post mining total plantation area will be 192.40 Ha.
Apart from above 9.17 Ha Plantation will be done at R&R site outside the
lease area. So greencover is almost upto the premining stage.
Topsoil shall be progressively and concurrently utilized during
physical/technical reclamation of backfilled area, thus obviating the
necessity of storage of topsoil separately.
Proper afforestation / plantation are to be carried out for greenbelt
development.
11.3.5 Impact on socio-economic condition & control measures
The major impactsare given below:
i. Displacement and rehabilitation / resettlement of PAFs, including change in
culture, heritage & related features.
ii. Loss of agricultural land
iii. General improvement of economy of area.
iv. Creation of new employment opportunities.
v. Increase in revenue of the state exchequer.
Control Measures
Two village are likely to be affected due to mining & its related activities of
proposed projects. Total PAF’s involved are 316. These families will be
resettled and rehabilitated socially, culturally and economically as per latest
R & R Policy of Govt. of Orissa, May, 2006
CMPDI
Job No.706135 Chapter 11, Page - 10
11.3.6 Impacts on flora and fauna Impacts:
As this is an existing mine, normal mining activities are expected to
continue in the area which will result in modification of landscape. However,
Changes brought about in the landscape, due to mining will be reclaimed as
per Post Mining Plan.
As the forest within lease area and in near vicinity is already degraded,
presence of wild animals is minimal. However, the forest of the neighboring
Forest Division is anticipated to support faunal ecosystem.
Control Measures:
The enhancement of forest area should be done through technical and
biological reclamation of backfilled area, arboriculture / afforestation,
compensatory afforestation, creation of greenbelt and avenue plantation.
Water body created by the final voids will be beneficial to flora and aquatic
ecosystem as the area is prone to water scarcity.
Top Soil Management during the mining phase is highly recommended for
restoration and reclamation of mine spoil sites through nutrient rich top soil.
The mine water should not be discharged to neighboring water bodies. If
required, water is discharged only after suitable treatment. No adverse
impact on downstream aquatic life of surface water courses is expected.
Green Belt Development for abating air pollution and enhancing green
cover.
11.3.7 Impact on hydrology & hydro-geology and control measures
(i) Impacts
Siltation and chocking of water courses.
Deterioration of water quality & pollution of water bodies.
