2.0 INTRODUCTION OF THE PROJECT / BACKGROUND INFORMATION
Identification of project and Project Proponent:
The quarry activity is for extraction of Colour granite over an extent of 2.893
Ha. in Survey No. 308/1 (Old Sy.N0.308) of Billekallu (V), Aspari (M), Kurnool
District, Andhra Pradesh.
The Promoters
The quarry activity is for excavation of Color Granite would be undertaken by
Sri. G.N.SUSHEEL KUMAR Managing Partner of the company. The quarry
activities will e undertaken under the supervision of mines manager.
Need for the project and importance to the region
India is one among the leading countries in mining and export of granite and
is rich in granite reserves. Geologically, the southern and eastern belts of the
Nation are abundant in granite deposits. Different shades of granites are
available in abundance in Tamil Nadu, Andhra Pradesh, Karnataka,
Maharashtra, Assam, Bihar, Rajasthan, Odisha, Meghalaya and Madhya
Pradesh. Indian Granite Stone has become the most sought-after and
extensively used stone material in building construction and massive
structural works throughout the world, and it is well known in the
International market, not only for its elegance and aesthetic quality, but also
for its durability.
The Granite Industry has received a wider publicity and corporate importance
in the last few years. The industry is emerging now as a thrust-export-area
with several corporate houses, supported by expert professionals trained in all
aspects, entering the sector with sophisticated world-class machinery and
making it an organized one. Many overseas buyers, including the Japanese,
are the regular importers of the Jet Black Material, which is considered to be
the world's best variety and is found in abundance in Tamil Nadu, Andhra
Pradesh and Karnataka.

India is one of the leading nations in the production and export of Granite and
other stones. Granite is a very hard crystalline, igneous or metamorphic rock
primarily composed of feldspar, quartz and lesser amounts of dark minerals.
India has vast resources of granite with about 110 varieties of different
colours and textures such as black, grey, pink, multi coloured, etc. These
varieties are used to produce monuments, building slabs, titles, surface plates
etc. However, popular varieties are mainly found in South India.
Granite in the form of slabs and tiles has several attractive features, which,
inter alia, includes extra-fine mirror-polish, scratch-free glossy surface and
durability. Granite can be compared very well with other floor and wall
application materials such as ceramics and marble.
Granites are now mined in most of the Indian states for use as construction
material and road metal but production of dressed granite blocks and slabs
from Andhra Pradesh, Karnataka, Rajasthan and Tamil Nadu are highly
priced. In India there are 43 granite processing units of which 12 are in
Andhra Pradesh, 13 in Karnataka, 3 in Rajasthan, 14 in Tamil Nadu and 1 in
Odisha. During the last five years exports have grown steadily by about 10%
a year but this growth rate may increase even more in the near future. New
companies may not be entering the industry but many existing companies are
steadily increasing their production capacity to meet demand.
New technology investments are being made with the aim of increasing sales
and reducing costs. In the last few years CNC machines have been employed
in many factories for making complicated designs. Usually the diamond tools
and other consumables are imported, to the extent of 80% of total demand,
and amounting to between 5 and 6 million US dollars per year.
Total Granite production in the Indian industry is estimated to be about 350
to 400 containers a month. (A curious unit - when referring to blocks the
normal term used is cubic metres, in slabs, the measurement unit is square
metres or square feet, while in the gravestones the reference point tends to
MAHATHI MINERALS PRE-FEASIBILITY REPORT

be containers). As mentioned before, the entire production is exported.
Presently about 180 to 200 containers are exported to Europe, approximately
50 containers a month are exported to United States, 40 containers to Japan
while the rest are sent to Australia, New Zealand, South Africa and other
countries. The months of November, December and most of January are
considered to be the low season when monthly production drops to about
half. An average container has a price of US$ 18000 to US$ 24000, depending
on the materials used and the complexity of the designs, thus the total
industry size is estimated to be approximately US $ 85 million.
Exports
Every month about 10,000 to 12,000 cubic meters of granite stones are being
exported to China and other countries. Every year, the granite stone business
turnover crosses over Rs. 500 crore in the district. It has also become a good
source of income for the railways, which has constructed special platforms for
transportation of granite to Kakinada and Chennai ports for export to China.
The stone is exported to China where it is polished and then marketed to
Japan and other Asian countries. The cranes deployed for lifting of huge
blocks of granite at the railway stations were also earning lakhs of rupees.
Besides, it is also providing employment to several labourers and others.
India has one of the largest reserves of granite in the world and
exported Rs 2,600 crore (Rs 26 billion) worth of the stone in the past
years. Granite exports this fiscal are expected to touch Rs 2,800 crore
(Rs 28 billion) and nearly one-fourth of these exports is accounted for
by monument stones.
About 85-90 % of the total granite production in the country is for
exports. So after the recession period is over the industry will again
regain its demand .This is the best time for an entrepreneur to venture
into this sector.
MAHATHI MINERALS PRE-FEASIBILITY REPORT

Last fiscal, the total exports of granite and marble from India had
crossed the Rs 4,000 crore marks with the US accounting for the bulk of
the consumption (40%).
The granite industry in Rajasthan has been growing at 50% annually.
But this growth has serious social and environmental costs. As the
water sources are being depleted, forcing farmers to become laborers in
the granite industry.
Rajasthan Granite mining is an approximately Rs 800 crore industry
today; it forms 95% of India’s dimension stone exports.
Imports
Granite importing countries such as the US, China, Italy have reduced their
requirements. India's granite and natural stone exports could be down by 15-
20 per cent per year according to CAPEXIL (formerly Chemicals & Allied
Products Export Promotion Council).

Geology of lease area:
The Subject area belongs to a small mound with a height of 8 M gently
sloping towards East direction. The area is exposed with multi Color
Granite Sheet Rock intruded with Quartz veins. This subject area is
exposed with sheet rock of pink and black color granite. Either side of the
area intruded in to the Granite Gneisses, it indicating it will be youngest
suits of Granitic rocks. The peninsular gneissic complex comprises
gneisses (migmatite), gray granite, and Pink Granite and Gneissic granite.
The gneiss in general show banding due to alteration of light colored
quartzo-feldspathic minerals and dark colored biotite or hornblende
minerals. These rocks may be separated in to two distinct groups namely
the massive foliated types occur as low dome shaped hillocks. The
intrusive relationship of the granite rock is evident by the presence of
tongues and apophyges within the older rocks and the occurrence of
xenoliths of the older rocks within the granite.
BRIEF DESCRIPTiON OF LITHO UNITS:
The Color Granite Minerologically consists of Quartz, Plagioclase feldspar
as essential minerals and other mafics Boitite and hornblende, etc., as
accessory minerals with fine to medium grain. The Pink Color grains and
the black colour spots are very attractive for this Granite .Fresh rock
surface is unweathered and it is categorized as Grade 'A'. The Granite
available in the demarcated area is useful for Cutting and Polishing purpose
and gives mirror image after polish.
The Rock belongs to Archean age. The area is a slightly undulated hillock.
Due to crisscross jointing the quartz veins are less and it is useful for
dimensional stones. The Q.L. applied area may yield a good deposit of
Granite, which shows uniform in grain size and widely spaced joints.

QUARRYING CARRIED OUT
Details of Quarrying Operations: Lease is yet to be granted. The
Preliminary survey has been done. The Q.L applied area does not contain
any forest cover. The applied area does not consist any wild life.
RESERVES
Geological traverses in the quarry and the study exposures in the vicinity of
quarries facilitated to access the shape and size of the deposit in the area. It
is a elevated Deposit rising 8.0 M above ground level within the quarry lease
area. The surface of sheet rock is wavy and irregular.
Method of Estimation of Reserves
The calculation of reserves of prospects, deposit of mine is done at every
stage, right from preliminary to lost stage of exploration and mining.
Based on the prospecting work carried out and the present exposure of the
boulders & sheet rock and the observations made in the adjacent Quarry the
reserves of the area have been estimated by the following parameters. The
proved zone is 13 m and probable and possible zones are 4.0 m each and the
recovery factor is taken only 25 % and it may vary in depth. The reserves are
estimated by the Cross Sectional Method.
Section wise calculation of Colour Granite reserves are given in the following
table.

MINING
Open Cast Mining
The Granite in the quarry lease area is exposed on the surface. Hence, it is
proposed to mine the Colour Granite by open cast, semi-mechanized
methods, by developing the benches of 6 M height with shallow drilling and
blasting. The development of benches will be maintained @ 600 safety slopes.
Therefore, mining operations are to be carried out in this area in 2 stages.
1) Development
2) Production
Stage -1
The removal of big size and under sized boulders will be cleared in the quarry
lease area for the next five years by using excavator.
The Hard Rock exposed will be subjected to drilling, blasting and splitting
from mother rock.
Stage - 2
After removal of weathered and Semi Weathered Rock under sized boulders.
The quarrying will be followed in the form of linear cut method. This involves
loosing of the primary block from mother rock. Hence primary cutting will be
done by line drilling method where close spaced parallel holes along straight
line will be made. Line drilling method is used for separation of primary
blocks.
i) Once the free face is developed in working place, the primary cuts are
taken up over a maximum length of 10 mtrs to a width of 3 mtrs and to
a depth of 6 mts depends upon the joints availability. These dimensions
are confirmed as for field studies. Primary block will be cut into
secondary blocks by Jackhammer drilling and wedge cutting and this
block will be dislodged from in-situ position by an excavator.
MAHATHI MINERALS PRE-FEASIBILITY REPORT
16
ii) Line drilling method will be used for cutting the primary blocks which
involve drilling & Blasting.
iii) The holes are charged with low explosive catridge like gun powder and
non-delay detonators for smooth blasting.
iv) The use of delay detonators causes fragmentation and cracks in rocks.
The non detonating cords are inserted into the holes and the holes are
stemmed with muck and plugged at the mouth and fired.
v) Thus the block will separate from the mother rock, which is pulled off
from the face with cranes or shovel.
Drilling
Drill holes of 2.0 - 6.0 M depth will be drilled in a staggered pattern at 3 m
interval:
i) Drill hole Diameter 32 mm up to 2.0-6.0 M long
ii) Depth and Inclination of drill hole
Generally drilled vertically in an alignment, drilled.
iii) Explosive Type
Delayed detonators with cartridges
Production Proposed for the next five years (2017 -18 to 2021 -22)
For the purpose of optimizing the production most of these quarries are
operating since long.
Production Proposed for the next five years (2017 -18 to 2021 - 22)
It is proposed to produce 13875 m3 of Granite during next five years plan
period with an average annual production of 2775m3from an area of 5000m2.
Benches of 6 m height will be developed during the plan period in depth of
previous year workings successively.

depth is 30 m . Hence ground water table will not have any impact due to
the mining operations.
ENVIRONMENTAL MANAGEMENT PLAN
AIR ENVIRONMENT
The pollutant emitted from quarrying activity will be dust; and major sources of
dust will be due to Quarrying operations and vehicular movement. The following
measures will be adopted in quarrying to eliminate the fugitive dust emission.
Wet drilling.
Water sprinkling on Quarry haul roads & approach road for dust
suppression.
The dust rising due to drilling will be controlled by covering the drill
rods with cloth, dust extractors will also be employed.
IMPACT DUE TO VEHICULAR TRAFFIC
• Maximum an average of 2 trucks / trailers per day will be required to
transport granite to out side agencies.
• The existing road is capable of absorbing this additional traffic.
• Dust suppression will be taken up along the haulage roads & approach
roads.
WATER ENVIRONMENT
WATER REQUIREMENT
The Granite Quarrying activity requires 13.8 cum/day of water. This
includes water for Drilling, identification of defects/cracks in granite blocks,
Dust suppression and domestic purpose. Water required will be sourced
from bore well of nearby village. The following is breakup of it.

WASTE WATER
The only source of waste water generation will be sanitary waste water of 0.6
KLD, which will be treated in septic tank followed by subsurface dispersion.
NOISE ENVIRONMENT
The main source of noise generation will be vehicular movement and the
drilling of boreholes. In the Quarry lease area silent blasting will be done by
using Chemical Compound. The following will be noise control measure:
The machinery will be maintained properly to reduce the noise.
The protective noise reducing gear like earplugs.
Plantation.
SOLID WASTE
75% Solid waste of rocks 41,625 m3 will be generated in this Granite quarry for
the period of 5 years. The Northern side of the area is selected for dump yard
for next five years and the waste will be stocked over a length of 45 m with
width of 35 m to a height of 12.0 m. Step dumping will be resorted. This
material can be utilized to fill the pits after quarry operations are over. When
the dumps reach their optimum height suitable greenery will be grown on this
dumps to stabilize them.
GREEN BELT DEVELOPMENT
