Lakshmi Stone Crusher Pre-Feasibility Report Perecherla Village, Medikonduru Mandal, Guntur Dt., 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 Road Metal. It is used in infrastructure development. 2.2 Brief Information about the Project The mining lease area of 2.10 Ac., is located in Non-forest, Government land. Open cast mining is followed and it has been proposed to produce approximately 8,000 cu. m./annum of Road Metal. The nearest habitation is Perecherla Village located at a distance of 0.5 Km due NW of Quarry Lease. 2.3 Need for the Project and Its Importance to the Country or Region The demand for Road Metal has increased due to rapid industrialization and growth in infrastructure. So the number of Road Metal producing quarries is increasing in India. Due to bifurcation of State, there is a huge demand for Road Metal. As per EIA notification 2006 project proponent is submitting the proposal to get Environment Clearance for QL area of 2.10 Ac. 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 20 workers. It will provide employment to the people residing in vicinity. 2 M/ s.

It is NNE – SSW trending in Southern part and charge to NE – SW, West of Eluru. 7 M/ s. Lakshmi Stone Crusher Pre-Feasibility Report Perecherla Village, Medikonduru Mandal, Guntur Dt., A.P 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 Present area constitutes part of Western Charnockite zone represented mainly of Charnockite and basic granulite with minor banded iron formation. Lithologically the lease area is underlain by Charnockite, which is fresh looking, greasy, dark coloured with domination of hypersthenes, blue quartz minerals in it. The Charnockite in the area forms dome shaped, steepy sloping hills. The rock is medium to coarse grained texture composed of greasy quartz, hypersthene, orthoclase and plagioclase with or without garnet. The rock is massive, with widely spaced vertical to sub vertical joints trending in NE-SW direction. It is observed that sheet joints are absent. Owing to its compact and hardness charnockite with stand to weathering and form huge, steepy sloping dome shaped hills in the area. 3.5.3 Exploration Road Metal quarries as the lease area is located on undulating land with surface relief of 17 m. The Road Metals found to be normal in that area, the deposit is being worked out to an maximum depth of 25 m only. 3.5.4 Reserves Reserves of Road Metal 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: 8 M/ s.

Only proved reserves were considered for calculating the mineable reserves. The details of reserves blocked under benches & safety/buffer zone are given in table below: A. Total Proved Reserves (m3) : 90202 B. Reserves Blocked under Benches (m3) : 9670 C. Reserves Blocked under 7.5 m Buffer zone : 7918 (m3) D. Mineable Reserves [A-(B+C)] (m3) : 72614 Yearly production : 8000 Life of mine : 72614/8000 =9.08 Say 9 Years 100% recovery of the Road Metal is considered from the quarry. 3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS 3.6.1 Method of Mining The Road Metal lease area is exposed on the surface. Hence, it is proposed to mine the Road Metal by open cast, using semi-mechanized method, by developing the benches of 6 M height with 2 slices of 3 m and 1.5 M bench width with shallow drilling and blasting. The development of benches will be maintained @ 40 - 600 safety slopes. 9 M/ s. Lakshmi Stone Crusher Pre-Feasibility Report Perecherla Village, Medikonduru Mandal, Guntur Dt., A.P Drilling Drill holes of 1.5 – 3.0 m depth will be drilled in a staggered pattern at 3 m. interval: i) Drill hole diameter : 32 mm up to 1.5 – 3.0 m long ii) Depth and inclination of drill hole : Generally drilled vertically in an alignment iii) Explosive type : Detonator Fuse/Anfo with detonators It is proposed to produce 40000 cu.
