NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY AND 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 in this sector, 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 & Colour granite for domestic & international market. Chemical grade Multi colour Granite has high, specific levels of Calcium Oxide (Cao), Magnesium Oxide (MgO), or both. Additionally, chemical grade Multi colour Granite has a high level of purity in that it contains very low levels of residuals typically found in Multi 5 SEPTEMBER 2017

6 Colour Granite composites such as, silica, clay, organic matter, iron oxide, and siliceous skeletal fragments. The optimum chemistry and purity of chemical grade Multi Colour Granite makes it ideal for Granite dimension stone is used in buildings, bridges, paving, monuments, and many other exterior projects. Indoors, polished granite slabs and tiles are used in countertops, tile floors, stair treads and many other design elements. It is also consumed in chemical industries like Indoors, polished granite slabs and tiles are used in countertops, tile floors, stair treads and many other design elements, etc. As the Multi Colour Granite mining operations in the proposed Quarry will employ about 18 persons directly and about 100 persons on indirect basis through allied opportunities in logistics, trading, repining works etc good employment potential will arise in this internal rural backward area, which will provide a great fillip for raising income levels and standards of living in the area. 6. DEMAND SUPPLY GAP The quarried Black Granite blocks are either exported as raw blocks or processed as value added products such as slabs, tiles, fancy items, Monuments, precision surface plates for engineering application in their own captive granite processing unit situated at KARUR district. The export market for granite is china, European Country, North America, Middle East, Far East, Japan, Taiwan & Canada besides catering local markets. Products and Application areas of Granites: Broadly there are six categories of granite products rough blocks, slabs, panels, tiles, monuments and others. Granites are most adoptable as interior veneers in sky scrapers. In architecture, granites are mostly used for artistic veneers as they enrich other aspects of buildings. Slabs, Panels, Tiles and Monuments: Granite in the form of slabs of various sizes is mainly used in building monumental institutions, commercial and residential buildings. Slabs : A semi finished block of rectangular size with one side polished and the other outside sawn and thickness in the range of 20mm upto 20 cm. are used for interior wall panels in the building. Panels: Panels are used for covering the interior surface of the buildings, as tabletops and as interior wall paneling. Size of panel range from 50 cms x 100 cms upto 100 cms x 100 cms and thickness correspondingly varying from 20mm to 50mm. 6 SEPTEMBER 2017

7 Tiles: Granite tiles are used as flooring material and also for wall cladding most preferred size is 30 x 30 sq. cms with 10mm thickness though sizes vary within the range 15 x 10 sq.cms and 60 x 60 sq. cms. Tolerance requirement in the international market on thickness is generally 0.1 cm to 0.2 cm. Monuments: Indian Black Granite is being exported in finished / semi-finished form for making monuments and tomb-stones for graveyards. Granite with good polish are mostly selected for making memorials ranging from simple markers and head stones to elaborate monuments and mausoleums. Some export of red granite monuments have also begun recently. Other Uses: In India granite is used as kitchen platform, kitchen sink, nameplates, foundation / inaugural stones etc., Granites ashtrays; flower vases and other art pieces which have both domestic and export markets. Other uses for dressed or cuter shaped forms of different sizes are as flagging stones in the form of flat slabs or rectangular or irregular shapes over steps, walk ways, parks and terraces, parking streets and highways or other traffic areas with rectangular blocks. Less known is the fact, that granites find important applications in the engineering fields as they possess high stability, non-denting and wear resistance qualities. These engineering grade granites are used in the construction of bridges, piers, sea and river walls, dams and related structures, bridges, super structures, grade separations and retaining walls. Granites are often used for the manufacture of inspection equipment, like surface plates, parallels, cubes, squares, straight edges, measuring prisms, guide ways of precision instruments and other metrological aids such as in weight measurements. 7. INDIGENOUS PRODUCTION There is no import of Black Granite at present in India. India especially the southern India has good resource of Black Granite and has a great demand in the international super market. Indigenous Black Granite almost shares more than 50% requirement in the world. 8. EXPORT POSSIBILITY Not envisaged. 7 SEPTEMBER 2017

14 The hard rock terrain of Archean to late proterozoic comprises predominantly hornblende biotite gneiss, North east South west trending and their magmatic derivatives supracrustal sequences. The geological sequence of the area adopted the mining lease is described as follows : AGE ROCK FORMATION Top Reddish soil Recent Dolerities Migamatites Migamatitic Precambrain Hornblonde Biotite Gneiss complex Pyroxene granulites Dolerities Hornblende Biotite geniss dharwar Archean Peninsular Gneiss The ferromagnesian minerals impart the black colour, hardness and compactness to the rock. The rock has a hardness of 6.5 to 7.5, specific gravity 2.8n to 3.3 wear factor unit weight 3.2 tonnes/cu.m Strike = Trending east and west direction Dip = Almost vertical dipping i. 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: (Proposed 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: There is an overburden on the deposit. Boulders are exposed on top of the Black Granite. The wastes are generated during the mining period is m 3 shall be proposed to Backfilling to the Middle Side of the lease area. This material can be utilized to fill the pits after quarry operations are over. d) Separation of large primary Blocks from the mother rock by pre - splitting (Primary): i) 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 14 SEPTEMBER 2017

15 method where close spaced parallel holes along straight line will be made. Line drilling method is used for separation of primary blocks. ii) Once the free face is developed in working place, the primary cuts are taken up over a maximum length of 10mts to a width of 3mts and to a depth of 6mts 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. iii) Line drilling method will be used for cutting the primary blocks which involve drilling and blasting. iv) The holes are charged with low explosive cartridge like gun powder and non-delay detonators for smooth blasting. v) The use of delay detonates causes fragmentation and cracks in rocks. The nondetonating cords are inserted into the holes and the holes are stemmed with muck and plugged at the mouth and fired. vi) 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 proclaim. 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 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.
