Underground mine entry and development - enhanced productivity and safety

摘要

69% of India's energy balance is dependent on coal-fired power plants. India has a current installed power capacity of 170 GW. Even if we consider a long term projected growth at 8% GDP, to meet the demand growth India has no other alternative, but to increase installed power capacity to 300 GW by 2020.Out of 250 billion tonnes of total reserves only 80 billion tonnes can be effectively mined by opencast mines with the current acceptable stripping ratio. Moreover, getting environment clearance and land acquisition is a lengthy procedure.So to meet the target of UGM coal production of 125 + million tonnes, by 2025 the only option that is left with coal mining industry in India is to introduce mass production technology at a very fast pace. What are the essential desirables for introduction of underground mass production technology?
