  1. Modernisation of Opencast Mining Technology For Higher Production and Productivity T.K.Nag CMD NCL

  2. STRATEGIC IMPORTANCE OF INDIAN COAL SECTOR • Around 77% of coal consumed met through indigenous source • CIL produces 81.73% of India’s current coal production Coal – India’s Primary Source of Energy * Others 9.4 % SCCL 8.9% CIL 81.7% Coal Production : Company -wise Share Sector-wise Supply Share from CIL Sources ** Others include cement, sponge iron, fertilizer. Bricks etc * Others include captive producer ,TATA STEEL, Meghalaya & Other PSUs 2 Source : Coal Controller

  3. Open Cast Mining in Coal India Limited • Spread over in Eight States • ~ Jharkhand, WB, Orissa, CG, MP, UP, Maharashtra & Assam • Operates 430 Mines through 82 Areas • OC Mines-175 • Contribution of OC has crossed 93 %.

  4. Existing Scenario – Opencast Mining • Dragline • Shovel-Dumper Combination • Surface Miner • In-Pit Crushing & Conveying

  5. Existing Size & Population of Equipment- CIL Mines OC Mines: Draglines ( 5 m3 to 30 m3) : 36 Nos Excavators (1.2 m3 to 42 m3) : 704 Nos Dumpers (35 T to 240 T) : 2829 Nos Crawler Dozer (320 HP to 850 HP) : 916 Nos Drill (100 mm to 350 mm) : 676 Nos Source : CMPDI
