塔拉壕矿软岩回采巷道支护参数优化研究

Research on Support Parameter Optimization of Soft Rock Mining Roadway in Talahao Mine

塔拉壕煤矿2101辅运顺槽埋深129 m,巷道直接顶及老顶主要为泥岩及砂质泥岩,属于软岩顶板。掘进期间2101辅运顺槽掘进效率较低,准15.24 mm锚索锚固力不可靠,巷道存在安全隐患。针对以上问题,对回采巷道支护参数进行优化调整,节约了支护成本,提高了掘进效率。

The depth of the 2101 auxiliary transport roadway is 129 m in Talahao mine,and the immediate roof and main roof of the mining roadway is mainly mudstone and sandy mudstone,belonging to soft rock roof. During the excavation,the 2101 auxiliary transport roadway exists many safety problems,and the tunneling efficiency is relatively low. And the force of 准15.24 mm mable is not reliable. In order to solve these problems,the supporting parameters of the roadway are optimized and adjusted,and the cost of supporting is saved,and the driving efficiency is improved.
