破碎顶板岩层掘进与支护研究

Research on excavation and support of broken roof strata

本文以破碎岩层的巷道掘进为基础具体介绍了乌石山矿区破碎巷道的掘进与支护方式,通过对破碎岩层顶板的支护与管理,降低了巷道垮塌风险,对井下支护工程有一定的指导意义。

Based on the roadway excavation of broken rock stratum,this paper introduces the excavation and support methods of Broken Roadway in Wushishan mining area.Through the support and management of broken rock stratum roof,the risk of roadway collapse is reduced,which has certain guiding significance for underground support engineering.
