E. Rambabu in Sy No. Gap Area of Thirumalarajapuram Village, Palasamudram Mandal, Chittoor District by the Asst. Director of Mines & Geology, over an extent of 1.00 Ha. for a period 10 years. Sri. E. Rambabu has proposed the project located in the above mentioned notified area and the lessee has been in this business since the last 10 years. PFR-I PROJECT: Road Metal & Building Stone PRE-FEASIBILITY REPORT APPLICANT: Sri. E. Rambabu 2.2 Brief Information about the Project The mining lease area of 1.00 Ha. is located in Government land. Open cast semi mechanized mining is followed and it has been proposed to produce approximately 15436 Cu.m/annum of building stone material. The nearest habitation is Thirumalarajapuram village, which is at a distance of 1.25 km. 2.3 Need for the Project and Its Importance to the Country or Region The demand for building stone has increased due to rapid industrialization and growth in infrastructure. So the number of building stone producing quarries is increasing in India. Building Stone and M-Sand have to produce as they form the aggregate in the concrete mixture used in the construction industry. The Indian Railways also requires the material for the maintaining the existing network and also for the never ending expansion. As per EIA notification 2006 project proponent is submitting the proposal to get Clearance for production capacity of 15436 Cu.m/annum from District Level Environmental Appraisal Committee/District level Impact Assessment Authority of Andhra Pradesh constituted by MoEF&CC, GOI for the purpose of grant of quarry lease for which Notification is issued. 2.4 Demands-Supply Gap There is huge demand since the material is used extensively in Construction, Railways, Roadways and many other sectors. 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 21 workers. It will provide employment to the people residing in vicinity. PFR-II PROJECT: Road Metal & Building Stone PRE-FEASIBILITY REPORT APPLICANT: Sri. E. Rambabu 3.0 PROJECT DESCRIPTION 3.1 Type of Project Including Interlinked and Interdependent Projects, If Any. The proposed mine area is of 1.00 Ha. area, No interlinked projects are associated with this project. 3.2 Location of the project The mining lease area is located in Survey No. Gap Area of Thirumalarajapuram Village, Palasamudram Mandal, Chittoor district, Andhra Pradesh. The mine lease area falls in Survey of India Toposheet No.: 57 O/08 Google map is given in Figure-1.

Rambabu 3.3 Details of Alternate Sites No alternate site was considered as the project is mineral specific and site specific. 3.4 Size or magnitude of operation The mine has lease over an area of and the 1.00 Ha. production rate is 15436 Cu.m/annum. The lease follows open cast semi mechanized mining. 3.5 Geology and Reserves 3.5.1 Topography The Quarry Lease area is a gently sloping ground at the foot of a mound in East side of the lease boundary. Ground level is sloping down in East with a gentle relief of 8-10m. Boundary pillars D have max elevation of 165 m MSL whereas the boundary pillars B & C have the least elevation of 144m MSL. The area is almost flat with an outcrop of a Granite cutting the site across between point B and C. No public roads are passing through the lease area. 3.5.2 Geology The subject area is Granitoid gneiss belong to Peninsular Gneissic Complex of Archean age. The outcrop exhibits multiple sets of joints both closely spaced and widely spaced as such it is most suitable for quarrying Road Metal and Building Stone. 3.5.3 Exploration Since this is a fresh mine no existing work has been done. Reserves Geological reserves are given below in Table 3.1.

E. Rambabu Life of the Quarry: Mineable reserves/Annual production=370485 /38486= 9.63 years *(Source: Mining plan) 3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS 3.6.1 Method of Mining The quarrying in the sanctioned area is of open cast method other than fully mechanized mining method with drilling and blasting. The ROM will be sized and sorted in the crusher established outside the quarry lease area loaded on to tippers and tractors using JCB, Mining will be carried out by formation of benches of height 6 m each. Considering the technical parameters like surface topography, quality variations, geo-technical aspects are required for production and extraction of building material in the area. It is proposed to work from the deposit by adopting benches formations with ultimate pit slope of 45°. The benches height and the width will be maintained as specified by D.G.M.S. The width of the working benches shall not be less than the height. The year wise production and development plan indicates the site for disposal of waste, site for afforestation as shown in map. The plan showing position of the working pit proposed for extension etc. Due care has to be taken in designing the benches and advancing the benches for production. The ground water table is much below the proposed working level.

Rambabu 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 material and dumping in stock yard. Loading of the building stone material will be done mechanically by tippers and transported from the quarry to the required site. The rejected material will be dumped separately. 3.7.1 Use of Mineral The extracted material will be used in Construction, Railways, Road ways and many other sectors 3.7.2 Processing No processing at site is involved. 3.8 Resource Optimization/ Recycling and Reuse Not envisaged. 3.9 Availability of Water Its Source, Energy/ Power Requirement and Source 3.9.1 Water Requirement Water is required only for drinking purposes and dust suppression. The number of working people is around 21 so the total water requirement will be around 3.0 KLD. This water will be supplied from bore wells of nearby area. 3.10 Quantity of Wastes to be Generated (Liquid and Solid) And Scheme for their Management/ Disposal 3.10.1 Solid Waste Generation& its Disposal There is no mineral reject or sub-grade mineral in this quarry.
