摘要
Abstract
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.关键词
