摘要
在2号、3号煤层层间距相对较小并含有部分松软破碎岩层,且3号煤以上相应2号煤层已被采空的情况下,通过在3518工作面部分巷道的试验,分析总结出在上述条件下使用锚杆、锚索进行支护的可行性操作方法,对煤矿的安全生产可起到一定的指导作用。
Under the near-distance layer combined with partial soft-broken rock-mass and 2 seam mined over 3 # seam between 2 # and 3 # coal seam, the feasible methods of adopting boltanchor rope to support roadway were summarized by the partial roadway＇s experiment of No. 3518 face, and it has certain direct action for mine safe production.
