摘　　要：针对复杂穿层巷道的难以支护问题,以七采区回风大巷为工程背景,通过现场实测和地质雷达对该回风大巷的围岩松动圈进行监测,根据悬吊理论、松动圈理论设计支护方案,提出了锚网+钢带+喷浆+锚索+注浆联合支护方案,通过FLAC3D对支护方案进行模拟和分析,最后结合现场实际情况进行分析,验证支护方案合理性。In view of the difficult support problem of complex cross-layer roadway,with the return air roadway in No.7 mining area as the engineering background,the loose circle of surrounding rock of the return air roadway was monitored by field measurement and geological radar.According to the suspension theory and loose circle theory,the support scheme was designed,and the combined support scheme of anchor net+steel belt+shotcrete+anchor cable+grouting was proposed.FLAC3Dwas used to simulate and analyze the support scheme,and finally,the rationality of the support scheme was verified by analyzing the actual situation on site.
