Min Mec Consultancy Pvt. Ltd. EXECUTIVE SUMMARY OF ENVIRONMENTAL IMPACT ASSESSMENT (EIA) AND ENVIRONMENTAL MANAGEMENT PLAN (EMP) FOR GARE IV/6 COAL BLOCK, MAND- RAIGARH COALFIELD FOR JINDAL STEEL AND POWER LIMITED. (EXTENT 381.42 HA) 1.0 INTRODUCTION 1.1 General Jindal Steel & Power Limited and Nalwa Sponge Iron Limited, registered under Companies Act, 1956 have been allotted by Central Government for mining coal from Gare-IV/6 Block and supply it on an exclusive basis to JSPL for DRI manufacture near Raigarh which is about 50 km and 40 km respectively from the coal block. Mining lease has been acquired for the period of thirty years. The total mine lease area is 381.42 Ha (942.526 acres), which lies within the villages Lamdarha, Saraitola, Gare, Khamharia and Karwahi. Out of 381.42 Ha, 93.64 Ha is forest land designated as Chhote jhad ke jungle and Bade jhad ke jungle (Unclassified forest). 1.2 Location and Communication The Gare sector is located in Gharghoda tehsil of Raigarh district of Chhattisgarh state. The district headquarter, Raigarh, is situated southwest of Gare-IV/6 sub-block at a distance of about 45km. The ML area is located between latitude 22° 08’ 04” to 22° 09’ 48” N and longitude 83° 29’ 07” to 83° 30’ 24” E. The leasehold area forms part of Survey of India, toposheet No. 64 N/12.

Ltd. A total of 77.712 million tonnes of net ‘Proved’ reserves and 80.3852 million tonnes of ‘Indicated’ reserves of grades varying from B to G have been estimated in the entire block. While the reserves in respect of quarriable seams Viz. IX, VIII, VII and VI fall in the ‘Proved’ category, the same in respect of seam III, II and I with potentiality for underground mining fall in the 'Indicated' category. The reserves of seam IV, which too has underground potentiality, however, fall in both the ‘Proved’ and ‘Indicated’ categories. The reserves considered for quarriable proposition in seam IX, VIII, VII and VI amount to 73.98 MT. The remaining reserves of 84.1124 MT falling both under the ‘Proved’ and ‘Indicated’ category are amenable to underground mining. 2.3 Coal quality The coal and OB computation upto VI seam is given in Table 4.

Extractable excluding mining losses 66.371 155.17 2.338 2.4 Mining method Crawler mounted pneumatically operated down the hole drilling rigs will be used for drilling 200-250 mm dia drill holes in overburden. R.B.H drills will be used for drilling 110/115 mm dia holes in coal. After shot holes are drilled into the horizontal bench cut by the shovel, the faces are blasted using explosives and detonators. Coal is also extracted after blasting off the coal faces. The excavation shovels deployed for coal mining will be used for loading the coal at the face. Large dia holes of 200-250 will be drilled in order to excavate on an average of 13.35 million BCM (Bank Cubic Metre of OB) per year. A powder factor of 0.30 to 0.35 kg per BCM has been adopted for overburden. The powder factor for coal has been adopted as 0.2 kg/m 3. 2.5 Transportation The OB will be transported by 25/50 T R.D trucks to surface dumps and later on, as soon as decoaled area is available suitable for backfilling, to the Executive Summary for Gare IV/6 Coal Block of Jindal Steel & Power Ltd. 5 Min Mec Consultancy Pvt. Ltd. site of backfilling. The coal will be transported by 25 T R.D. trucks to the coal receiving pit/crusher and the proposed washery, at the pit head and the washed coal will be transported to the plant by the trucks. FE loading machines with 2.5 m 3 /6 m 3 coal bucket will load the coal into trucks for haulage to plant or railway station. All the coal produced from the mine will be directly transported to washing plant proposed to be established within the ML. The clean coal from the washing plant will be transported to the DRI plants. 2.6 Infrastructure The mine design incorporates appropriate water gradients to allow the collection of water in sumps for which proper pumping arrangement will be done. The mine project is located at a distance of 15 km to the west of the Tehsil town of Gharghoda.
