七五煤矿四采区巷道布置设计优化

Roadway Layout Design Optimization of No.4 Mining Area in Qiwu Coal Mine

针对七五煤矿井田断层较发育,开采过程中易引起冲击地压的问题,对矿井巷道布置进行了优化设计,分析了优化四采区巷道布置的具体方法,并确定了合理的大巷和断层保护煤柱。实践发现,经优化后的巷道布置大大提升了开采的安全性,并创造了一定的经济效益。

Aiming at the development of faults in Qiwu Coal Mine and the problem of rock burst easily caused in the process of mining,this paper optimizes the layout of mine roadways,analyzes the specific methods of optimizing the layout of roadways in the fourth mining area,and determines the reasonable main roadways and fault protection pillars.The practice shows that the optimized roadway layout greatly improves the safety of mining and creates certain economic benefits.
