GEOLOGY, COAL SEAMS AND THEIR STATUS
Three coal horizons i.e. Lajkura, Rampur & IB Seam occur in
Lajkura-II geological block of IB Valley Coalfields. The seams
occur in Barakar & Karharbari formation of Lower Gondwana. Only
Hingir Rampur Seam is being mined through Orient Colliery, Mine
No-1&2. The general
strike of HR Seam & bed is N 100 W & the true dip of the
seam is S 80
0 W. The gradient of
HR Seam varies between 1 in 6 to 30. The average thickness of HR
Seam varies from 25M to 30M including bands. The seam is inter
banded with coal, shaly coal, carbonaceous shale & shale. The
vertical parting between Lajkura horizon & Rampur horizon is
about 90M. The HR Seam has been split into 4nos of sub-seams namely
HR Seam-I, HR Seam-II, HR Seam-III & HR Seam-IV having
thickness of about 2.59M, 2.22M, 2.69M & 3M respectively. The
parting between HR Seam-I & HR Seam-II is 3M, the parting
between HR Seam-II &HR Seam-III is 13M and the parting between
HR Seam-III & HR Seam-IV is 3.5M. The average grade of coal is
G-9. At present, the depth of cover varies from 25M to 220M &
it is likely to increase on the dip side of the property. So far,

VENTILATION
Introduction:
The objective of any ventilation system is twofold. First, the
primary ventilation must course air
through the main airways to the immediate working area out by
the working faces, thus making
fresh air available for face ventilation, and then return the
contaminated air through return
(exhaust) airways to the surface. Second, the face ventilation
system must be designed to
effectively utilize the available air in the immediate working
area to sweep the working face, to
capture and remove dust, and to dilute and carry away gas, if
any, emitted during mining
activities. Without a properly designed ventilation system, an
efficient production cycle would
not be possible. The system should provide the required air
volumes and quality at reasonable
pressure losses, perform with minimum interference and cost to
production, and do so in the
most cost-effective way possible.
Furthermore, the primary ventilation system may be well
designed, but if the available air
brought to the working area is not properly utilized for
ventilating the faces where most workers
are located, the total system has failed (Bossard, et al.,
1982).
Ventilation Equipment
The mine is provided with two exhaust type fans i.e. one AF -100
(Axial flow )
installed at surface that provides adequate ventilation in all
the working of OC 1&2
mine and other one is A PV-200 (Axial flow ) has been installed
as stand- by . Auxiliary
fan (2 no.s) for LHD .Districts are installed to course air
within 4.5m at the working
face. There are 2 no.s of intake air way s and one return air
ways such as 6th incline
, 7th incline and 10th incline .

SUPPORT SYSTEM
Working districts are supported by roof-bolts with full column
grout as per approved ssr.
The general pattern of support at face is 3 bolts in a row with
spacing of 1.2 m between rows
and 1.5 m between bolts in a row. The 1st row of bolt shall be
put not more than 1.2 m from the
face. Side bolts shall be inclined towards the sides &
center bolts shall be vertical or normal to
bedding plane. Junctions are supported by additional 25 % roof
bolts. Roof stitching is also
practiced in addition to roof bolts in bad roof condition and
properly lagged with sleepers.
Anchorage testing machines are used for testing 10% of erected
roof bolts in each shift.
Anchorage testing is being done at half an hour, 2 hours, 24
hours & 28 days after erection of
bolts. Two anchorage testing machines are provided i.e. one in
each working district. The
tested bolts are properly tagged for its identification.

In order to determine the system of support to be followed, Rock
Mass Rating (RMR) is
Determined for the immediate roof, say, up to 2 m above gallery
height. For this purpose, generally, the
following parameters are considered:
Layer thickness,
Structural features,
Rock weathering ability
Rock strength, and
Ground water seepage.
-
Details of systematic support rules:-
Support at development workings--- The roof of the development
workings, not exceeding 4.2
m in width, within 10 m of the face is supported by 3 full
column cement grouted bolts in a row, with
the row spacing not exceeding 1.2m. The bolts in the same row is
so installed that their spacing does not
exceed 1.5m, and the maximum distance of the bolts from the
pillar side does not exceed 0.60m. The
last row of support shall not exceed 1.5m. Side bolts is fixed
at an inclination of 55-60 degrees from the
horizontal.
Support at junctions--- Every junction of the roadway
immediately out bye of the development
face, is supported with full column cement grouted bolts in a
manner that spacing of such bolts in the
same row does not exceed 1.5m and also row spacing does not
exceed 1m to ensure 25% extra support
at junctions.
GENERAL
a) The roof bolts used is of dimension 20-22 mm in diameter and
1.5m in length.
b) The bearing plates used is MS plates of size 15cm*15cm size
and 6 mm thick with center hole.
c) Quick setting cement capsules are being used for full column
grouting.
d) 3 cement capsules were inserted into each drilled hole and
hold in place with the help of roof bolts, rotated
a no. of times, then bearing plate is tightened to its place
with the help of the nut & bolt.
e) Support pressure taken up by the roof bolts is 8-10 tons
after 24 hours of installation.
ANCHORAGE TESTING:--
1. At least 10% of the bolts installed should be tested for
anchorage, by selecting bolts randomly.
2. Of the tested bolts 90% should be tested as follows:
Time elapsed after installation Load to be applied
30 min 3.0 tons
2 hours 5.0 tons
3. 01% of the bolts should be subjected to destructive
testing.

ANTICIPATED IMPACT AND MITIGATION MEASURES:
There will be impacts on air, noise, flora and fauna due to
mining and its related activities.
1. Air quality impact & control measures
The air quality of the OC-2 mine w.r.t SPM , NOx , SO2 , etc.
concentration levels is found to be within
limits of the prescribed standards at all stations located in
core and buffer zones & is being monitored
regularly. Therefore no effects either on human being or flora
and fauna is found to be observed as suitable
mitigation measures are taken to make the operation
eco-friendly.
The preventive measures in this context is listed below:
In Underground---
Regular cleaning of spillages to prevent dust being
airborne.
Water spraying at transfer points.
Regular ventilation survey as per statutory requirement.
Adequate firefighting arrangements in the mine.
Careful removal of loose coal from the abandoned coal face.
Prompt removal of wood cuttings, oil & grease from
underground workings.
-
On the surface---
Black topping of service roads to prevent generation of dust on
surface.
Water spraying on all roads to minimize dust generation.
Mechanized coal transport system.
Unmetaled roads are kept from ruts, pot-holes, etc.
Greenbelts around infrastructure sites, mine return & colony
sites.
Schedule of water spraying arrangement---
Water spraying by tanker in underground haul road.
Presently the spraying arrangement is carried out weekly,
fortnightly & monthly.
In some old working areas, spraying is done quarterly.
In tippler zone and transfer point area, spraying of water is
done by surface water tank.
2. Impact assessment on hydrology & hydro-geology and
control measures
-On surface water sources
There is no significant drainage traversing the area except over
land flow slopes.The major impacts are
water pollution due to oil & grease, contamination of water
bodies due to discharge of mine-effluents and
pollution from domestic & sewage effluents. Groundwater
aquifers may get disrupted and also due to
continuous pumping out of mine water, the water table of the
surrounding area may get lowered resulting
in scarcity of ground water.
Control measures:
(i) Domestic waste water is treated in soak pit and septic tank
combination provided to each unit.
(ii) Treatment of mine discharge water before discharging it to
surface water course.
(iii) Recycling of treated mine discharge water to achieve zero
discharge to the extent possible.
(iv) Provision of oil & grease trap, provision of drains
around coal dump / stock yard.
3. Impact assessment on noise quality and control measures.
Impact:
Abnormal and loud noise have auditory effect. But, the ambient
noise level of OC-2 mine is being
monitored regularly. Noise levels are within the limits of the
prescribed standard.
Control measures:
All vibrating machines are mounted on vibration absorbing
pads.
Enclosure of fan, etc. Adoption of personal protective devices
to all persons working in high noise areas.
Regular monitoring of noise levels at various points.
4. Impact assessment on blasting vibration and control
measures
Impacts:
Safe blasting measures are adopted .So, there will be no effects
on life, property and ambient noise.
Control measures:
(i) All provisions of coal mines regulations are followed.
(ii) Using the particular quantity of explosive as decided as
per conditions imposed by DGMS.
