摘　　要：北辛窑矿南翼回风大巷通过断层破碎带时,因围岩裂隙较发育、夹带部分裂隙水,造成巷道稳定性差,岩巷若采用“锚网索喷”支护,不足以保证岩巷围岩稳定及其安全使用;决定采用“锚网索+U型棚+注浆+喷浆”联合支护技术方案,并通过实时矿压监测巷道围岩变形;实践表明,联合支护技术方案应用后巷道顶板未出现明显变形,巷道支护质量逐步趋于稳定,能满足巷道的正常施工和安全使用。To solve the problem of poor stability in the south wing roadway of Beixinyao Colliery,it has been decided to adopt a combined support technology scheme of"anchor mesh cable,U-shaped shed,grouting and spraying",and to monitor the deformation of the surrounding rock of the roadway through real-time mine pressure monitoring,whose application practice shows that there is no significant deformation of the roof of the roadway,and the quality of the roadway support gradually stabilizes,which can meet the normal construction and safe use of the roadway.
