Gnaneswary Quarry Pre-Feasibility Report Konanki Village, Piduguralla Mandal, Guntur District, A. P. 2.0 INTRODUCTION OF THE PROJECT/BACKGROUND INFORMATION 2.1 Identification of Project and Project Proponent The proposed project area is found to have good deposits of Limestone (Minor). It is used in infrastructure development. 2.2 Brief Information about the Project The mining lease area of 0.809 Ha.is located in Non-forest, Government land. Open cast mining is followed and it has been proposed to produce approximately 1,06,875 Tons /annum of Limestone (Minor). The nearest habitation is piduguralla Village located at a distance of 2.5 Km due SE of Quarry Lease. 2.3 Need for the Project and Its Importance to the Country or Region The demand for Limestone (Minor) has increased due to rapid industrialization and growth in infrastructure. So the number of Limestone (Minor) producing quarries is increasing in India. Due to bifurcation of State, there is a huge demand for Limestone (Minor). As per EIA notification 2006 project proponent is submitting the proposal to get Environment Clearance for QL area of 0.809 Ha. from District Level Environmental Appraisal Committee/District level Impact Assessment Authority of Guntur constituted by MoEF, GOI for the purpose of operating the quarry lease for which Notification is issued. 2.4 Demands-Supply Gap There is huge demand since the material is used extensively in building construction infrastructure development. This project will help in reducing the Demand-Supply gap in the area. 2.5 Domestic/ Export Markets The material is used in the domestic market and in there is no scope for exporting the material. 2.6 Employment Generation Proposed mining is semi-mechanized method and this project operation will provide livelihood to the 25 workers. It will provide employment to the people residing in vicinity. 2 M/s. Gnaneswary Quarry Pre-Feasibility Report Konanki Village, Piduguralla Mandal, Guntur District, A.

P. 3.5 Geology and Reserves 3.5.1 Regional Geological setup The Eastern Ghat Mobile Belt (EGMB) in Andhra Pradesh occupying large parts of Coastal District, Prakasam, Guntur, Krishna, East & West Godavari, Visakhapatnam, Vizianagaram and Srikakulam Districts for more than 600 Km in length with maximum width of 100 Km in Northern District and tapers it to 20 Km in Southern District. It is NNE – SSW trending in Southern part and charge to NE – SW, West of Eluru. Stratigraphy & Lithology Eastern Ghat Mobile Belt in Andhra Pradesh is devided into 3 longitudinal zones based on the lithological characteristics. 1) Western Charnockite Zone (WCZ) 2) Central Khondalite Zone (CKZ) 3) Eastern Migmatite Zone The Southern half of the coastal belt is mainly represented by Western Charnockite zone with minor patches of Central Khondalite Zone like near Mangalagiri, where as in the Northern District of Andhra Pradesh, Central Khondalite Zone predominant with bands of Charnockite Rock. 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 8 M/s. Gnaneswary Quarry Pre-Feasibility Report Konanki Village, Piduguralla Mandal, Guntur District, A. P. 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 11/ith 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 35 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) : 252600 B. Reserves Blocked under benches (m3) : 22794 C. Reserves Blocked under 7.5m Buffer Zone (m3) : 27840 Mineable Reserves (A-(B+C)) (m3) : 201966 Average Annual Production : 32000 Life of the Mine : 201966/32000 = 6.31 Say 6 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. 9 M/s.
