煤矿深井软岩高应力巷道支护技术

摘要

埠村煤矿东区主要巷道埋深达到900m以上，属于深井不稳定地层。该巷道处于向斜轴底部高应力区范围内，巷道压力大，围岩比较破碎，变形大，稳定性差，采用普通锚喷网支护难以维持巷道的稳定。本文结合现场实际拟采用锚网喷加锚索梁联合支护巷道，在实践中取得了良好的效果，为类似地质条件下巷道支护提供了一套可借鉴的方法。%Bucun mine east area of mining depth is more than 900m, which belongs to the deep unstable strata. The roadway locates in the high stress area of the bottom of the synclinal axis , the roadway pressure is high, the surrounding rock is broken, deformation, the stability is poor, the ordinary bolt shotcrete support is difficult to maintain the stability of roadway. this paper combined the actual plans to use the anchor net and anchor support, and achieved good results in practice, provide a reference for similar geological conditions of roadway support.
