INTRODUCTION: NAME, AND TRAINING UNDER TAKEN IN SEMISTER (IN LONGWALL OR CONTINUOS MINER) MASS PRODUCTION TECHNOLOGY Indian Coal Sector India is the third largest hard Coal producing country in the world after China and USA. With 123.2 billion tonnes of proven coal reserves out of total geological reserves 298.9 billion tonnes as on the 1st April 2013. BP Statistical Review of World Energy 2013 estimates recoverable coal reserves of India as 60.6 Billion Tonnes, that is, 7.1% of World’s 860.94 Billion Tonnes recoverable reserves. Approximately 88% of Indian Coal reserves constitute Non coking coal with average GCV of 4500 K Cal/ Kg, of course with low sulphur. 90% of Indian Coal Production comes from opencast mines. MASS PRODUCTION TECHNOLOGY Indian Coal Sector (Contd) As on 31st March 2013 Nationalized Coal Sector, consisting of 12 Public Sector Companies of which Coal India Limited and Singareni Collieries Company Limited are majority stakeholders contributed 91.3% of Indian Coal Production during 2012-13. Balance contribution of 8.7% of national coal production came from Private sector consisting mainly of 21 Private sector companies for captive industries. Indian Coal sector has a robust demand which requires that the growth rate in Coal production is increased to 9% plus, compared to the present rate of 3.2% achieved during 2012-13. Indian Coal Production during 2012-13 has been 557.71 million tonnes, through 559 coal mines as against a demand of 772.84 million tonnes. Despite of adding 17.75 million tonnes more than 539.95 million tonnes produced during 2011-12, we had to import 137.56 million tonnes of Coal during 2012-13, nearly 19.44%
