2.0 INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION

2.1 Identification of Project and Project Proponent

The project area is found to have good deposits of Colour granite. Granite is

used as a construction material for flooring, coverings and cladding, making of

kitchen articles, sculptures, etc.

2.2 Brief Information about the Project

The mining lease area of 1.295 Ha. is located in Govt land. Open cast semi

mechanized mining is followed and it has been proposed to produce

approximately 10373 m3/ annum of Colour granite. The nearest habitation is

Devarahalli located at a distance of 1.3 km due SE from lease area.

Sri S. Venugopal (Partner) has filed an application for quarry lease for Colour

Granite over an extent of 1.295 Ha, in Sy.No. 139/P of H.D. Halli Village, Agali

Mandal, Anantapur District, Andhra Pradesh to the Assistant Director of Mines

and Geology, Anantapur. DM&G, Ibrahimpatnam has decided in principle to

grant quarry lease for a period of 20 years. Notice.No.31321/R4-1/2017, Dated

19.01.2018.

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 colour Granite for

domestic market.

2.4 Demands-Supply Gap

The demand and supply for the colour 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.

3.5 Geology and Reserves

3.5.1 Regional Geological setup

The Geological formations in the Anantapur District can broadly be divided in

distinctand 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 Devanakonda 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 Subject area belongs to small mound rising to a height of about 2m with

boulders from ground level. The granite is exposed as a sheet rock in the centre

portion with gently slope and soil is covering on top portion. However the granite

sheet is well exposed without any burden at higher altitudes. It represents late

magmatic injection of closepet granite.

The commercial name for colour Granite is Multi Colour Granite of Anantapur. The

rock is essentially composed of Quartz, orthoclase feldspar and biotite. The rock is

compact and moderately hard with less joints.

3.5.3 Exploration

1) Production proposed for the next five years:

In the present area there is a cluster of quarries of different sizes. For the purpose of

optimizing the production most of these quarries are operating since long, As recent

rules and regulations of DMG & APPCB & APPMC, all Quarries should follow

Mining Plan , EC, CFE & CFO, also be noted that DMG issuing the permission

based up on above all required Papers.

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 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: (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:

Mainly the over burden is excavated with the help of excavators of 30-35 Ton

capacity. Sometimes hard rock poses the problem for digging by excavators.

Hence, it requires loosening by mild blasting with the help of licensed blaster

such as foreman and mate. The weathered rock and useless sheet rock can be

drilled by jack hammers and blasted them into fragments /pieces to facilitate

their removal.

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.

PRE-FEASIBILITY REPORT

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:-

Major boulders exposed are used for small size marketable 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

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.
