Limestone, Shale and Quartzites of the Kurnool Super Group are exposed in the Palnad area, these are locally known as Palnad formations. The stratigraphic succession of the palnad series is as follows

Algonkean

Palnad Series

Nandyal Shale

Koikuntla Limestone Panyam Quartzite's Owk Shale Narji Limestone Banganapalli Quartzite -------------Thrust----------- KADAPA SUPER GROUP

Kadapa Super Group

Of the above sequence, the narji limestone, attained maximum thickness and spread over large area. It has extensively found between Machavaram – Dachepally - Gurzala area. The own shale and other younger formation are exposed only in Veldurthi & Durgi area.

3.5.2 Local Geology

Narji Limestone formation of Kurnool group exposed in this area is well bedded, gray to white in colour and of flaggy to massive nature. The trend of lime beds varying considerably in this area due to structural disturbance. Fine laminae of argillaceous and silt found in limestone of this area. There are two types of limestone seen in the area 1) Siliceous Limestone 2) Argillaceous Limestone In this area siliceous limestone occupy in large area. Mostly composed of calcite with minor constituents of quartz, sericite, pyrite, anatase and goethite minerals. Structurally, Palnad limestone hosts number of faults in different direction mainly of NNW - ESE, ENE - WSW, NNE - SSW trends. Vertical joints in limestone are trending in N- S, N 20° E- S 20° W, N 60°- 80° W- S 60°- 80° E, out of these joints some are open and some are filled with calcite and quartz veins. Siliceous, flaggy lime stones are hard, compact and massive which are being mined for in these are for manufacture of slabs, which are used as flooring material in construction activity.

3.5.3 Exploration Limestone (Minor) quarries as the lease area is located on undulating land with surface relief of 6 - 10 m. The Limestone (Minor)s found to be normal in that area, the deposit is being worked out to an maximum depth of 20 m only.

3.5.4 Reserves Reserves of Limestone (Minor) are estimated by Cross Sectional Area method. One cross section was drawn in the lease area and the summary of reserves are given in the below table:

Summary of Geological Reserves A. Total Proved Geological Reserves (m3) : 617951

B. Reserves Blocked under benches (m3) : 32704

C. Reserves Blocked under 7.5m Buffer Zone (m3) : 88493

Mineable Reserves (A-(B+C)) (m3) : 496754

Average Annual Production : 23275

Life of the Mine : 496754/23275 = 21.34 Say 21 years

Considering the recovery of the Limestone (Minor) from the quarry is 95%, the 5%

will be the generated in the form of sub grade during quarry operations, which will be

stacked separately in stock yard for further sorting and sizing.

3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS 3.6.1 Method of Mining

The Mosaic Chips (Limestone) in the quarry lease area is exposed on the surface with sheet. Hence, it is proposed to mine the sheet by semi-mechanized methods, by developing the benches of 6 M height with 3 M bench width. With shallow drilling and breaking with rock breakers. The development of benches in the sheet rock will be maintained @ 60° safety slopes. Therefore, mining operations are to be carried out in this area in 2 stages. 1) Development 2) Production Stage - 1 The weathered limestone will be scraped out so that the underlying fresh mineral will be exposed for quarrying.

The limestone beds exposed will be subjected to drilling and rock breakers from mother rock. Rock Splintering: The loose material will be loosened with drilling the holes with jack hammers aided with compressor or using rock breakers to separate the mass. Fragmentation the Mass: For fragmentation of the mass from mother rock, the line drilling and breaking method are in use. Stage - 2 After removal of weathered top layer The sheet will be subjected to splintered into 300 mm sized and transported to the crusher units for crushing to the sizes of 5 mm, sized chips and < 100 mesh powder. Drilling Drill holes of 1.5 - 3.0 M depth will be drilled in a staggered pattern at 3 m interval. It is proposed to produce 24,500 tonnes of limestone during next two years plan period with an average annual production of 23,275 tonnes from an area of 3266.67 M2. Benches of 6M height and 3 M will be developed during the plan period in depth of previous year workings successively. The sub grade that will be generated will be to the tune of 5% in the form of intercalated waste generated from the joint planes in the rock and dust generated during the drilling of holes.

a) Removal / Excavation of O.B. and other Quarry Waste:

5% of Waste is generated in Limestone (Minor) quarry. 3.7 Raw Material Required Along With Estimated Quantity, Likely Source,

Marketing Area of Final Product/S, Mode of Transport of Raw Material and Finished Product No raw material will be required in the proposed project. The operation involves the extraction of Limestone (Minor) and dumping in stock yard.
