摘要
为了减少巷道破岩量,提高巷道过断层掘进效率,保证施工安全,在2305巷下山掘进过正断层时,对顶板破碎岩体采用撞楔超前支护,保证了施工巷道安全快速过断层破碎带,取得了较好效果。
In order to reduce the amount of rock breaking in the roadway,improve the tunneling efficiency and ensure the safety of the construction,in the 2305 lanes,the breakage of the broken rock in the roof is used to ensure the safe and fast crossing fault zone of the tunnel,and the good results have been obtained.
