2.0 INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION
2.1 Identification of Project and Project Proponent
The proposed project area is found to have good deposits of Black granite. Granite is
used as a construction material for flooring, coverings and cladding, making of kitchen
articles, sculptures, etc.
Sri.R.C.Kishore Kumar is the Proprietor of the proposed project. He had significant
experience in granite mining.
2.2 Brief Information about the Project
The mining lease area of 2.00ha is located in Government land. Open cast semi
mechanized mining is followed and it has been proposed to produce approximately
1386m3/ annum of Black granite. The nearest habitation, Kottapalle village is located at
a distance of 0.69 km due South from lease area.
M/s. Kishore Granites has filed an application for quarry lease for Black Granite over an
extent of 2.00 ha, in Sy.No:121, of Nellmanda Village, Somala Mandal, Chittoor District,
Andhra Pradesh to the Assistant Director of Mines and Geology, Chittoor on 04-01-
2011.
The Director of Mines & Geology, Hyderabad has decided to grant a quarry lease in favor
of M/s.Kishore Granites for a period of 20 years subject to submission of Approved
Mining Plan within a period of 6 months from the date of issue of notice
No.244/Q1/2005 dated 25-06-2005 as per Rule 12 (5) (C) of Andhra Pradesh Minor
Mineral Rules, 1966.

Mining plan was approved by Department of Mines & Geology letter no. 1019/MP-
PLMR/2012, Dated 07-04-2012
2.3 Need for the Project and Its Importance to the Country or Region
The demand for granite increased due to rapid industrialization and growth in
infrastructure. So the number of granite producing quarries is increasing in
India. Granite is the chief material for the export industries like monuments,
flooring slabs, Kitchen articles, sculptures & export. Based on the demand of
Granite, the lessee intends to produce the required quantity of Black Granite for
domestic market.
As per EIA notification 2006 the project falls under Category- B, the proponent is
submitting the proposal to get Clearance for production capacity of 260 m3/
annum of granite blocks from SEAC, SEIAA, A.P for the purpose of grant of quarry
lease.
2.4 Demands-Supply Gap
The demand and supply for the Black granite is growing which makes a lot of
scope for revenue generation. Once the stone is obtained after quarrying it is
further processed and supplied to industries.
India is amongst the leading exporter countries of stones in the world. The major
importers of Indian stones are USA, China, UK, Italy, Belgium, Germany, UAE,
Hong Kong, Spain, Taiwan, Netherlands, Canada, Turkey, France, Russia and CIS
countries. The growth is continuing and the demand for marble, granite,
sandstone and other dimensional stones and stone products is anticipated to
grow at around 15% CAGR.

2.5 Domestic/ Export Markets
Although granite is a minor mineral, it is a major contributor in foreign exchange
earnings. India is a major exporter of natural stone and granite, which is the
second largest foreign exchange earner for India besides iron ore in minerals
category.

3.5.1 Regional Geological setup
The Geological formations in the Chittoor District can broadly be divided in distinct and
well marked groups and older group of Metamorphic rocks belonging to Archean and
Younger group of Sedimentary rocks belonging to the Proterozoic age the later cover
part of Punganur block. The remaining parts of District is Occupied by Archean rocks

which consist of Schist, Gneisses, Quartz veins and basic dykes. The Archean rocks have
suffered considerable degree of tectonic disturbances, as a result of which the rocks
have been metamorphosed and recrystallized.

3.5.2 Local Geology
The Black Granite in the Distinct form of occurrence as dolerite dyke swarms in either side of the Grey granites & Gneisses. The Subject area belongs to a hillock extended in EW direction and gently sloping towards South direction with Black Granite Sheet Rock intruded as Dolerite dyke. The rock is highly puckered, sheared and faulted and has schistosity trending between EW with moderate to steep dips in either southerly and Westerly directions. 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.

3.5.3 Exploration
Present Status:
There are four pits in the Q.L area and it is observed in the pits that the surface
consists of the soil and bouldey waste only and a small quantity of granite blocks are
recovered and the undressed blocks are laying around the pits. The present lessee has
no information about the production. The boulders are highly weathered and lot of
defects like Colour patches and cracks are there. However immediately below this zone
lies the sheet rock which is productive zone.
The Q.L. area does not contain any forest cover. The area does not consist any
wild life.

3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS
3.6.1 Method of Mining
a) Type of Mining:
Open cast method of mining is carried out in this mine by manually and semi
mechanization by using compressor operated jack hammer drills, excavators, and
dumper etc, Transportation will be made by trucks to dispatching point.
b) Brief Description: (Existing method of working)
The mining operations are carried out by semi-mechanization as open cast mining.
Hydraulic excavator and compresses operated jack hammers were used for cutting the
rock. Close spaced drilling of 0.2m was adopted along a straight line and charged with
low explosives to avoid feather cracks.
c) Removal / Excavation of O.B. and other Quarry Waste:
The middle of Northern side of the Q.L.area is selected for dump yard for next five years
and the waste will be stocked over a length of 60mts, width of 40 mts, to a height of 8
mts as a earmarked in plate No.4. Step dumping will be resorted. This material can be
utilized to fill the pits after quarry operations are over. When dumps reach their
optimum height suitable greenery will be grown on these dumps to stabilize them.

d) Separation of large primary Blocks from the mother rock by pre-splitting
(Primary):
The mining 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 10m to a width of 3m and to a depth of 6m 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.
ii. Line drilling method will be used for cutting the primary blocks which involve
drilling and blasting.
iii. The holes are charged with low explosive cartridge like gun powder and non-
delay detonators for smooth blasting.
iv. The use of delay detonates 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.
e) Sub-Division of large Primary Blocks into Secondary Block:
This will be done drilling close spaced holes (along a line) down to the depth and the
secondary block will be removed easily by just pulling it with the help of proclain.
Close spaced holes will be drilled to the half the length of the block on either side of
it by using wedges blocks can be separated.
f) Production of Commercial Blocks:-
After primary separation the rock mass will be carefully examined to avoid hair line
cracks, mineral segregations and veins etc., The dressing of the rough blocks will be
Project: Black Granite Mining Project PRE-FEASIBILITY REPORT Applicant: M/s. Kishore Granites
14
made by chipping the edges and geometrically equating the edges of the block at the
dressing yard. The rough blocks obtained after primary cut it will be dressed for
obtained good geometric shape of granite. Thus the commercial blocks are produced.
