Introduction of the project / Background information: (i) Identification of project and project proponent: Background: There is a need to enhance power generation in the country from the present level of 148,000 MW to 380,000 MW by the year 2030 to achieve an economic growth rate of 8% to 9%. The major share of growth in power generation is through thermal i.e., coal based. Hence country’s coal requirement will have to be enhanced to 1300 MT. To compensate the decrease in production from the closing mines and to meet the demand of coal in this region, the project proponent, Singareni Collieries Company Limited (SCCL), a Government Company is planning to open new mines in the new blocks. Adriyala Shaft Project was started in the year 2008. Environmental clearance was obtained for Adriyala Shaft Project for a production capacity of 2.144 MTPA vide letter No. J- 11016/258/2004-IA. II(M) dated 11-10-2004. In Feasibility report it is envisaged to deploy two Longwall units in this project. Due to drastic development in Longwall technology worldwide, it is proposed to deploy one high capacity Longwall unit instead of two and to produce 3.14 MTPA from the same mine. Identification of the project: Adriyala Shaft Project is an underground mine located in Adriyalla Project area(APA) of SCCL. Rated production capacity of the project is 2.144 MTPA. The grade of the coal varies from G5 to G9 over the life of the project. 3 Project Proponent: The Singareni Collieries Company Limited (SCCL) has been exploiting coal for more than 122 years in the 350 km stretch of Pranahita Godavari Valley Coal Field spread in four districts of Telangana viz. Adilabad, Karimnagar, Warangal and Khammam with man power of 62805 and is the second largest public sector under taking in the state. It is the only coal mining company in South India catering the needs of coal based industries in the region. SCCL is currently operating 16 open cast projects and 32 underground mines and has achieved coal production of 50.47 MT in the year 2013-14 and target for the year 2014-15is 55.00 MT.

Present proposal envisaged for expansion project: The project was granted environment clearance for a production capacity of 2.144 MTPA with two Longwall sets and 150m face length. Keeping in view of the changes in Longwall Technology globally, SCCL has decided to deploy high capacity Longwall Technology which is capable of producing more than 3.0 MTPA in the same minetake area by redesigning the Longwall face length with 250m. Hence it is proposed to increase the production capacity of the mine from 2.144 MTPA to 3.14 MTPA and to obtain environmental clearance for this production capacity under MoEF memorandum J-11015/30/2004-IA- II(M) dated 7/1/2014. 4 The following is the state of art equipment configuration of the proposed Longwall equipment. i) SL ii) Description iii) Technical details NO iv) CHOCK SHIELDS v) 1 vi) Support capacity vii) 1152 Tonnes (2 legged DTDA version) viii) 2 ix) Support Density x) 120 Tonnes per Sq.Mt (before cut xi) 104 Tonnes (after cut) xii) 3 xiii) Operating xiv) 2.8 to 3.6 m Range xv) 4 xvi) Support width xvii) 1.75 m xviii) 5 xix) Rapid Yielding xx) Gas operated rapid yielding valves of 1500 lpm and rock burst valve (DN 40 U) of flow rate of about 6000 lpm for each leg. xxi) 6 xxii) Controls xxiii) Batch controls of 5 to 10 + SIRSA for advancing the supports as per the movement of shearer automatically. xxiv) SHEARER xxv) 7 xxvi) Make xxvii) BUCYRUS DBT xxviii) 8 xxix) Type / Model xxx) EL 3000 xxxi) 9 xxxii) Haulage xxxiii) Jumbo track 2000 System-Track xxxiv) 10 xxxv) Electrical xxxvi) i). 2 X 860 KW for cutter drums motors xxxvii) ii). 2 X 125 KW for haulage xxxviii) iii). 200 KW for in built crusher xxxix) iv). 1 X 75 KW for hydraulics xl) 11 xli) Cutting height xlii) 2.8 m to 3.6 m xliii) 12 xliv) Operating xlv) 3.3 KV, 3-Phase, 50 Cycles voltage xlvi) 13 xlvii) Cutting capacity xlviii) 3000 TPH (while travelling up the hill at a gradient of 1 in 4 (about 14 dgrees) xlix) AFC l) 14 li) Face length lii) 260m long face + 10.5m spare liii) 15 liv) Capacity lv) 3X855 KW, 3.3 KV, 3-Phase, 50 Cycles, 1142 mm wide, high wear-resistant, PF6 Deck plate with minimum thickness of 30+25mm, 48X144/160 mm twin inboard chain of suitable speed and a minimum capacity to convey of 3100 TPH. lvi) BSL lvii) 16 lviii) Length lix) 29.5m with suitable overlap system lx) 17 lxi) Capacity lxii) 400KW, 3.3 KV, 3-Phase, 50Cycles/ sec. 1342mm lxiii) wide, high wear resistant, PF6 Deck plate with lxiv) minimum thickness of 30+25mm, 42X146mm twin lxv) in board chain, 2.06 m/sec speed, and a minimum lxvi) capacity to convey of 3200 TPH 5 The Adriyala Shaft Project is demarcated within the following boundaries: 1 North Proved fault F4-F4 2 South Straightened Bokkala vagu 3 East Dip side proved limit i.e. 670m depth of IV seam 4 West Existing GDK10/ GDK10A dip side boundary The total area of the project is 3.4 km2 covering 2.75 Km in strike direction and 1.25 Km in dip direction.
