摘要
基于高河矿W4307回风顺槽过断层带期间巷道顶板出现破碎、冒顶现象,导致巷道掘进速度降低、巷道支护困难、成型差等难题,通过研究决定采用注浆+架设钢棚进行联合维护,提出了事故预防措施,取得了显著成效。
Based on the problems of broken roof and roof fall during W4307 return air passing through fault zone in Gaohe Coal Mine,such as lower roadway driving speed,difficulty in roadway support and poor shaping,it is decided to adopt grouting+steel shed for joint maintenance through research,and accident prevention measures are put forward,which have achieved remarkable results.
