浅析煤矿掘进过断层技术及应用

Analysis on the technology and application tunneling passing through fault

掘进过程中经常遇到断层等复杂的地质条件现象,由于断层的出现,给巷道掘进造成很大的影响。陈四楼煤矿21013上顺槽通过采取后退挑顶法、光面爆破技术、综合支护技术、优化装载与运输系统,实现了断层带的快速掘进,对类似条件下巷道快速掘进具有一定的借鉴意义。

The complex geological condition such as fault, is often encountered in the process of excavation, which has a great influence on the roadway excavation because of the fault of the fault. During driving 21013 crossheading of Chensilou coal mine, taking back roof brushing method, smooth blasting technology, comprehensive supporting technology, optimizing the loading and transportation system, realize the rapid excavation of the fault, which has a certain reference to the similar conditions of roadway rapid excavation.
