2.3.1 Need for the Project and Its Importance to the Country or Region

Indian granite has a good market value in the world. Granite is an igneous, magma-formed rock that is generally made up of quartz, feldspar and mica. These minerals combine in varying percentages that account for the color, veining and crystallization patterns that make each granite deposit unique.

2.4 Demands-Supply Gap

The demand and supply for the color granite is growing which makes a lot of scope for revenue generation.

The earth crust is filled with different types of rock which ranges from igneous, sedimentary and metamorphic rocks. Granite is an igneous rock formed from the cooling of magma in an exothermic process. Granite popularly known as chippings /gravel is a very hard stone good for building and construction works globally. It is a common and widely occurring type of intrusive felsic, igneous rock. It has a medium to coarse texture occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. It can be pink to dark gray or even black depending on their chemistry and mineralogy. Granite is a hard, usually grey, stone used for building and


6


the most common rock type on the continental land masses. It is widely distributed throughout the continental crust of the earth and is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents.

Its hard nature made it a very suitable and durable material for most Civil Engineering and Construction works. It is used in various ways as in;

Road Construction and Dimensional stones Building of Houses, Bridges and Drainages Manufacture of Marbles and Flooring Tiles Production of cement blocks Interior Decorations Art works (Antiquities) etc.

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 the second largest exporter of raw granite after China and ahead of Brazil and South Africa.

3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS 3.6.1 Method of Mining

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 points. (Rail head/Port)

Brief Description: (Existing method of working):

The mining operations are carried out by semi-mechanization as

open cast mining. Hydraulic excavator and compressor operated jack

hammers were used for cutting the rock. Close spaced drilling of 0.2m


16


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 South-Western side of the area is selected for dump yard for next

five years and the waste will be stocked over a length of 40mtrs. with

width of 35 mtrs. To a height of 9.0 mtrs. as enmarked in plate

no.4.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.

d) Separation of large primary Blocks from the mother rock by pre-splitting (Primary cut)

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 is taken up over a

maximum length of 10 mtrs with a width of 3 mtrs and to a depth of 6

mtrs. 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-situe position by an excavator.

Line drilling method will be used for cutting the primary blocks which involve drilling and blasting.

iii) The holes are charged with low explosive catridge like gun

powder and non-delay detonators for smooth blasting.


17


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 seggregrations 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.

Extent of Mechanization: a. Since it has been decided to undertake semi-mechanized mining

Operations, the following mentioned mine machinery will be

deployed. Excavator — One (Bucket capacity 1m3, Boom length,

7m, Model: Tata Hitachi 200Lc)

p) Drilling and Blasting :

Drilling and Blasting plays vital role in determining the size and shape of rough

blocks. Drilling pattern is important in developing a working face and also

preparing the rough blocks suitable for their use in appropriate processing

units. Even though, there are no important places in and around the area,

blasting will be carried with all precautionary measures.

g) Drilling Parameters:

i. Drill holes diameter – 74/Pmm.

ii. Depth and inclination of the blast holes. 3 meter in case of

Separation primary blocks depending on the block size. Then the drill-hole

will be vertical.

iii. Spacing and burden : 1.5 x 3m.

iv. Stemming and charging of the blast hole. The Blast hole will be charged with

100 grams of explosives and filled with clan pills subsequently; the shot hole will

be stemmed.

v. Explosive type (1) Slurry based explosives or Gun Powder.

h) Broad Blasting Parameter :

Drill-Hole patterns for primary and secondary smooth blasting. Uniform

single line, equidistant holes (line drilling) will be deployed for separation

of blocks from mother rock. In the case of sheet rock the primary drilling

will be in the form of equidistant vertical holes to take out blocks of Gang

Saw.
