CHAPTER 1
INTRODUCTION
1.1 This chapter contains brief information on the proposed stone
quarry project at Village Alathur in Mandal B.N.Kandriga in district
Chitoor of Andhra Pradesh. This quarry is in possession of M/S Ultra
Tech Cements Ltd. (UTCL). Total lease are is 15.674 ha. Actual mining
will be over 4.9 ha. Please see Annexure 1 for copy of mining lease.
1.2 Proponent:
M/s Ultra Tech Cement Ltd. (UTCL) is one the corporate companies
under Aditya Birla Group. It has a board of 12 Directors. (Annexure 2)
Demand for building material and road metal is in A.P.
1.3 Project brief:
Proposed project for mining and processing of material (sized stone
metal) 1200 TPD (432 m3) per day. This is the basic raw material -input
to road and building construction activities. Economics of both
these activities depends on the lead to the user agency. Also,
demand for ‘manufactured sand’ is growing as observed during
market search.
Extraction of stone metal and its dry beneficiation at site itself will be
compatible with ‘environmental setting’ and transportation of
assorted material from the site will be economical.
This project ensures employment to about 30-35 local persons. In
addition indirect employment in trades related to mining e.g.
transportation, work shop will be available.

2.4 Proposed operations:
Semi-mechanized open cast stone mining is proposed. Drilling,
blasting, crushing and screening is proposed. Deposits in lease were
worked earlier by another agency since this area has been ear-
marked for quarrying stone metal. Mining has been permitted by
Director, Geology & Mining. Lease is possession of proponent.
Reconnaissance survey has indicated that there are no sensitive
receptors or eco system around the lease.
Main activities will be
1. Mechanical mining of ROM @ 432 m3 /per day.
2. Production of marketable materials/ aggregate (0 -6, 6-12 & 12-20
mm) along with manufactured sand.
Mining:
Mining will involve drilling, blasting, loading of mined materials into
tippers, unloading the tipper into a jaw crusher, screening and
segregation of materials of different sizes and transportation to
destination.
Segregation process
It is estimated that about mining @ 600 m3 ROM per day will yield
about 432 m3 of finished product. Flow of material from mine pit to
screen is given below :

o Products i.e. sized materials will be transported in covered
truck, / tippers as per its intended use.
o Undersized/oversized materials during the process will be
recycled as shown in the flow sheet.
o Fines will be used for manufactured sand (0-6 mm).
o Water requirement will be for the potable purposes since
process is dry and for dust control. Source will be tankers from
the nearby village.
16
o Power requirement will be 600-800 kV(A). Supply from
APTRANSCO will be requested. Stand by D.G. set has been
planned.
o Likely quantity of low grade material will be about 170 m3 /day.
It will be stored over about 1.5 ha area.
o Mine working will be followed inline to Rules / regulation /
bylaws laid under Mines Act1952.
o Liquid waste will not be generated because all processes are
dry.
o Ground water table is beyond 45 m.
o Ultimate depth of pit will be 31 m. Hence water table will not
be intercepted.

CHAPTER 3
ENVIRONMENTAL CONCERNS
3.0 Probable environment –concerns during are schematically
shown below:
DRILLING
BLASTING
• All sources will be fugitive.
• Mining will be over 4.9 ha and crusher, screen etc will be over
about 6 ha from remaining lease area.
• Blasting & drilling will be below ground level.
3.1 Land is owned by M/s UTCL. Land is to be used for mining. It is
non agriculture land. There are no sanctuaries, national park or
eco-sensitive areas within 10 km radius.
3.2 Some infrastructure for administrative purposes has been
created after lease was granted. It includes office, weigh bridge,
water for security personnel etc.
MINING – Fugitive PM emissions
Controlled blasting as per DGMS norms’ Water sprinkling Macadamized roads
Material handling Hopper Crushers Vibratory screens Conveyors
Water sprinkling in hopper & crusher
Closed conveyor
Closed vibratory screens

Plate 4 : Rest room for labour
Plate 5 : Security room

There will be provision for a 600-800 kV(A) DG set. Crusher area will
be about 2 ha. Explosive magazine will be provided as per Explosive
rules 2008.
Space for OB/ soil dump will be provided. There would be mine-
road inside mining lease area and for transportation of finished
products.
3.3 Soil cover is almost absent. Only 42158 m3 soil will be
generated in seven years.
3.4 R & R is not required.

CHAPTER 4
PLANNING BRIEF
4.1 UTCL proposes to start project activities immediately after
presentation of prefeasibility report if the Committee permits. This is
earnestly requested since many construction and road projects
depend on supply of stone metal.
Moreover,
i) R& R is not required ,
ii) This government land has been earmarked for stone mining,
iii) UTCL is capable of meeting the infrastructural demand for
mining in environmentally compatible manner without any
delay and immediately.
4.2 Proposed infrastructure :
There will not be any colony within the lease. Additional connectivity
will not be required because existing roads and communication is
adequate.
Local sources of water viz. hand pump would be adequate. Water
required for dust control will be the rain water collected in existing
pit.
A glimpse of usual infrastructure/control systems usually adopted by
UTCL are presented in the following plates
M/s UTCL will provide enclosures and scaffolding at all the transfer
points within crusher area. These are shown in following
photographs.

PLATE 6 : ENCLOSURES AT ALL TRANSFER POINTS &
SCAFOLDED PREMISES OF CRUSHER AND WATER SPRINKLING
CLOSED CONVEYOR & DELIVERY IN SCAFOLDED
22
PLATE 7 : RECEPTOR
Such preventive measures will minimise dust generation from crusher
area.
Therefore, adverse enviornmental impacts on air quality are not
expected.
4.3 Impact on noise levels
Sources of noise will be drilling, movement of vehicles, unloading at
jaw crusher, vibrators, etc. Expected levels from these sources are
respectively 65-70, 70-75, 85, 90 dB(A). Blasting will cause noise and
vibrations. It is reiterated that all these activities will be over a hillock
i.e about 60-80 m above ground level.
23
4.4 Remedial measures:
• PPE will be issued to the drillers.
• All vehicles will be properly maintained and machinery will be
properly lubricated.
• Jaw crusher, vibrators, etc have been provided with enclosures
and will obstruct the propogation of sound waves.
• Blasting will be carried out by professionals according to the
DGMS norms.
4.5 Impact on land:
o Land/ lease area is barren and has not been designated for
any other use besides stone quarrying.
o It is not prone for supporting natural vegetation due to
erosion of soil in the past.
4.6 Cost estimate :
Production cost will be about Rs. 300 per/ MT on an average.
Capital investment will be Rs. 3-4 crores including crushing plant
UTCL project may provide employment to 30- 35 persons.
4.7 Conclusions:
It can be concluded that the project is environmentally compatible,
financially viable and would be in the interest of construction
industry thereby indirectly benefiting the masses. Moreover
employment to local people will be an additional advantage.
24
o It is possible that at the end of lease period a pit/crater will
be created over the lease area. This will hold rainwater for
prolonged period because basalt is not known to permit
percolation.
4.8 Remedial measures:
o In this particular case OB is not adequate to backfill the pit
after ceasation of mining. However, low grade material will
be used for part filling of the pit.
o Mine pit area will be barricaded to prevent any
unauthorised entry.
o Accumulated water can be used for plantation. One cubic
metre pits will be made, filled with soil or garbage to provide
