Ground Control Technology for Mass Exploitation of Coal Deposits with Continuous Miner: A Review of the Indian Scenario

摘要

This paper presents ground control technology associated with acontinuous mining operation for mass exploitation of undergroundcoal deposits in the Indian coal mining Industry It shows thatcompetency of roof strata and performances of continuous minersare safer, than other coal mining method as well as productiveand economical. Continuous miners keep playing a major rolein the underground coal mining industry for their safety and aswell as their productivity. Regarding past experiences in Indiancoalfields, Chirimiri and Jhanjara mines have achieved exceptionalperformances, with a potential for over 500,000 tonnes per year.Tandsi mine has difficult roof conditions and does not typicallyachieve high production and productivity. Even so, the difficultroof conditions have been controlled with modern “world bestpractice” roof bolting systems and an output of up to 1,200 tonnesper day has been achieved. It can further be emphasized that if thistechnology is implemented properly it will bring an unfathomablechange to the Indian mining scenario. There are many minesin India that may have potential and economic viability withground control technology concepts for installing continuousminer systems and beginning mass exploitation of undergroundcoal deposits.
