摘要
矿井巷道在掘进过程中经常遇到断层、陷落柱、煤岩体结构破碎带等地质异常,给井巷工程的安全生产带来极大的威胁,因此掌子面前方地质异常构造的超前探测意义重大。本文以巷道掘进掌子面前方的断层及岩溶陷落柱的超前探测为例,论述了单点探测理论及方法在矿井巷道掌子面上的超前探测的应用。
Roadway excavation process often encountered in the fault column,broken rock structure with coal and other geological anomalies,to the Mine Safety works to bring a great threat to the working face in front of the geological significance of abnormal structures of advanced detection significant.In this paper,the fault in Front of Face Roadway Excavation and karst collapse columns advanced detection,for example,discusses the single-point detection theory and method in mine tunnel on the tunnel face advanced detection applications
