Land Srikakulam Mining Methodology The Colour Granite in the quarry lease applied area is exposed on the surface with boulders. Opencast semi- mechanized method by developing the benches of 6m height. Wire Saw cutting will be deployed based on the favorable conditions. The development of benches in the sheet rock will be maintained @ 60° safety slopes. The separation of blocks from the mother rock will be carried out by drilling, wedge cutting, excavation will be done by the machinery. The secondary splitting, dressing of blocks will be done manually.

Srinivas Annexure of Form-1 ANNEXURE II Drilling Drill holes of 9m depth will be drilled in a single row with spacing of less than 0.3m and burden of 1.6m or more shall be maintained uniformly. This arrangement will yield rock size of 3m x 2m cross section. A bench height of 6m will be tackled in two steps. Drilling Parameters i. Drill holes diameter – 32mm upto 9m long. ii. Depth and inclination of the drill hole Generally drilled vertically in an alignment, however in primary cutting in the absence of sheet joints to develop bottom level horizontal holes also be drilled. iii. Explosive Type Not Applicable. Dressing After primary separation the rock mass will be carefully examined to avoid hairline cracks, mineral segregation’s 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 obtaining good geometric shape of colored granite A-6 Sri L. Srinivas Annexure of Form-1 ANNEXURE - III Water Requirement Water requirement of 15.6 KLD for the project is mainly for Domestic source, maintaining the green belt and also for sprinkling on the haulage roads to mitigate dust emissions. The water shall be drawn from nearby villages. The water requirement of the project is presented in Table A-3. Table A-3 Water Requirement S. No. Water Usage Quantity KL/day 1 Wet drilling operation 8.5 2 Water sprinkling on haul roads 5.5 3 Domestic @ 45 Ltr/ 1.2 4 Green Belt@ 2 times a day 0.4 Total 15.6 Domestic effluent of 0.9 KLD shall send to septic tank followed by soak pit. Site Services It is also proposed to provide the site services like Mines office and other statutory constructions like rest shelter, first aid, work shed and drinking water as required will be provided in the quarry area. Drinking water is supplying to the workers from the bore wells in the adjacent agricultural fields. A-7 Sri L. Srinivas Annexure of Form-1 ANNEXURE – IV Solid waste During the plan period operations a total rock mass of 756522 m3 will be excavated and 151304.4 m3 of granite blocks will be recoverable from this rock mass and remaining material of about 605218 m3 will go as mineral waste. The granite body exposed to the surface. Hence, the weathering on the surface of the rock closely spaced joints and shears along with inherent defects like Moles, Dark patches and acidic veins contribute a large extent of waste generation during the mining. The waste generated will be dumped in the NW of the quarry lease applied area (Within the quarry lease applied area) covering an area of 9050m2 with an average height of 6m with 45° slope angle will be formed. A retaining wall will be constructed around the dump for preventing the slanting of boulders. Waste Dumping The waste generated will be dumped in the NW side of the quarry lease applied area (Within the quarry lease applied area) covering an area of 9050m 2 with an average height of 6m with 45° slope angle will be formed. A retaining wall will be constructed around the dump for preventing the slanting of boulders. During the plan period operations a total rock mass of 756522 m3 will be excavated and 151304.4 m3 of granite blocks will be recoverable from this rock mass and remaining material of about 605218 m3 will go as mineral waste A-8 .
