摘　　要：为了避免工作面停采时预留保安煤柱受采动影响出现围岩变形现象,减少巷道维修费用,通过技术研究,对保安煤矿15110综采工作面提出了切顶卸压护巷技术。通过实际应用效果来看,切顶卸压后能够形成人工卸压通道,通过人工干预使围岩应力得到提前释放,降低了大应力对围岩产生的剪切破坏作用,取得了显著应用效果。In order to avoid the deformation of surrounding rock caused by the impact of mining on the reserved safety coal pillar during the shutdown of the working face,and to reduce the maintenance cost of the roadway,through technical research,a roof cutting and pressure relief roadway protection technology was proposed for the 15110 fully mechanized mining face of Bao’an Coal Mine.From the practical application results,it can be seen that the artificial pressure relief channel can be formed after the top cutting pressure relief,achieving early release of surrounding rock stress through manual intervention,reducing the shear failure effect of large stress on the surrounding rock,and achieving significant application effects.
