乐平矿务局采煤方法改革的认识与实践

Cognition and Practice on Promoting Reform of Mining Method

搞要:乐平矿务局北部矿区急倾斜煤层一直采用传统的斜切爆破采煤法,该采煤方法采区回采率低,坑耗高,煤质差,采掘接替紧张,安全状况差。从2001年起,积极改革采煤方法,促进了矿井安全生产。

The traditional angle--opening blasting mining method has been used in steep seam in the northern mining district of Leping Mining Bureau, which is regarded as irregular with low recovery coefficient, high pit consumption, inferior coal quality, tense mining relay and bad safety condition. From 2001, a newly--reformed mining method has been promoted to improve production safety.
