(Own patta Land-92.465 and government waste land-18.22) which is located at S.F No. 349, 350, 351etc, Village- Anandavadi, District- Ariyalur, State- Tamilnadu. As per EIA notification 2006 and its subsequent amendments later, the project activity has been categorized as “Category-A” due to of mining lease being more than 50 Ha.

This Feasibility report is prepared based on the Draft mining plan submitted for Approval to IBM. Project Proponent:

Tamil Nadu Cement Corporation Limited (TANCEM) is a state-government undertaking of Government of located in the Indian state of Tamil Nadu. It manufactures cement, AC sheets, hollow blocks, concrete and other building materials. Tamil Nadu Cement Corporation Limited (TANCEM) was incorporated on April 1, 1976 to take over and operate the existing cement plant in Alangulam, Virudhunagar with an authorized share capital of Rs. 18 crores.

TANCEM, as its expansion and conversion activities, set up Asbestos Sheet unit at Alangulam during 1981. TANCEM also took over during 1989, a Stoneware pipe plant from TACEL with a view to provide employment to the retrenched employees.

The company has its main objective in production of cement and cement based products and primarily caters to the needs of Government departments. Limestone being the main raw material, the company acquired and reserved enough limestone bearing lands in and around Alangulam and Ariyalur which are sufficient to run the cement plants for decades to come. Hence, the role of TANCEM in the development of state is immense.

M/s. Tamilnadu Cement Corporation Limited belong to Government of Tamilnadu enterprise is having two cement units, one at Alangulam and another at Ariyalur. The installed capacity of the Ariyalur cement unit is 5 lakh tonnes per annum. It is a modern

TANCEM has expanded the capacity of Ariyalur Works from 5 lakh tones per annum to 15 lakh tones per annum by installing the Green field plant and proposed to commission the unit on August 2018. 1.2 Brief Description of Nature of the Project Anandavadi Limestone Mine is an existing mine, hence this Project does not require any Forest Clearance as no forest land is involved or CRZ Clearance and Wildlife Clearance. The method of working is opencast (A category fully mechanized) adopting non- conventional method by deploying rock breaker for primary and secondary breaking eliminating drilling and blasting thus adopting eco-friendly mining. The method of working is opencast mining considering various technical parameters like surface topography, continuation of limestone deposit, quality variations, geo- technical aspects, required rate of production etc. The method of working is opencast (A Category fully mechanized) adopting non-conventional method by deploying rock breaker for primary and secondary breaking eliminating drilling and blasting thus adopting eco-friendly mining. It is proposed to work this deposit by adopting 4.0 m bench height. The width of working benches will be 6.0m. The main work comprises of overburden removal, using rock breaker for mining kankar & limestone.

The Following are the steps involved for winning limestone:

Primary and Secondary Breaking: Mega Rock Breaker of 150 TPH capacity will be deployed for primary breaking and dilution of oversize boulders which will totally eliminate drilling and blasting.

Loading and hauling: Excavator will be used for loading the material on to the tippers (hauling units) which will be used for transportation of mineral from the mines to crusher at plant site and for handling the overburden / reject.

Rock breaker will be used for primary breaking wherever required and also for reduction of oversize boulders instead of secondary blasting.

BENCH PARAMETERS: Bench height - 6m Bench Width - 8m Ultimate Pit Slope - 450 Depth of Mining - 21 m maximum up to 80 RL. The proved mineral reserves are 18.58 Mil.T of limestone, having the proposed exploitation for mineral of 1.5 million tons per annum; the life of the mine will come around 12.38 years, say 13 years. Hence the life of mine is 13 years only with respect to the proposed production rate.. However the life of the mining may be extended in future depending upon the availability of other fresh leases. 1.3 Need for the Project and Its Importance to the Country or Region Limestone is very important industrial mineral and is the principal raw material for the production of soda ash and clinker for cement etc. The entire limestone production from Anandavadi Limestone mine is proposed to be sent to Ariyalur cement Works, for cement manufacturing unit at Ariyalur. The

Mantec Consultants Pvt Limited Page 5

Pre Feasibility Report of Capacity Enhancement of Anandavadi Limestone Mine limestone produced from this Mining Lease will be used for manufacture of Cement in company’s factories in Tamil Nadu initially and can also cater to the need of the Ariyalur cement Works.

The existing mining & cement plant operations by TANCEM in Ariyalur area have brought improvement in social, infrastructural and employment sectors in the area. Besides above benefits, financial accruals will be derived by Central, State governments and Local Panchayat on account of royalty, cess, duties, DMF and NMET, etc, from project output.

Cement being a core infrastructural sector component, limestone supplies for cement Manufacture also assumes great importance. 1.4 Demand-Supply Gap

Limestone with at least 44% CaO is required in the ROM for manufacture of cement and limestone above 40% CaO can be used if beneficiation is provided or higher grade limestone is available which can be blended to upgrade the lower grade limestone upto 44% CaO. The quality of available high grade ore in Anandavadi limestone is of 47.5% CaO content and having less Fe2 O3 & MgO, and this can be blended well with the Kallankurichi deposit limestone materials which are having high Fe2 O3 and less SiO2. The present blending technique and raw mix design is given below. During the enhancement of limestone production and Cement capacity of plant, the blending technique and raw mix design will be modified according to the available grade of limestone and limestone from new mining leases in future. The entire mineral mined will be used for the manufacture of different types of cements in the own captive cement plant located at Ariyalur, and District along with limestone received from other leases.

1.5 Imports vs. Indigenous Production

The proposed project is expected to bring down the procurement of limestone from domestic as well as overseas suppliers. 1.6 Export Possibility

The entire production of limestone will be used by Ariyalur cement works. No part of the product is proposed to be exported. 1.7 Domestic/Export Markets The proposed mining activity is for obtaining limestone for indigenous consumption in manufacture of cement in Ariyalur cement works.

1.8 Employment Generation The anticipated employment, likely to be generated, is given in the table below. It includes managerial & supervisory staff directly employed by the company and skilled, semi skilled workers through contractual.
