俯斜综采工作面过断层技术与实践

Technology and Practice of Fully-mechanized Dip Mining Face Passing though Fault

针对木瓜煤矿10-208俯斜综采工作面回采过程遇7m断层的工程实际,通过采取降低采高、破底穿岩、放震动炮、单向割煤等手段,不仅顺利安全通过断层,而且提高了生产效率,节约了成本,为解决综采类似条件的工程问题提供借鉴。

When No. 10-208 fully-mechanized dip mining face met a 7-meter fault in Mugua Mine, some approaches, such as lowering mining height, breaking floor, blasting tremor, and one-way cutting, were used to realize the smooth passing-through in order to improve the produc- tion efficiency and reduce the cost. The study could provide a reference for the similar engineering problems in the fully-mechanized mining.
