摘　　要：分析4317孤岛工作面沿空掘巷顶板围岩窥视结果可知,巷道顶板围岩浅部存在裂隙、深部完整性良好,为增强王坡煤矿4317孤岛工作面沿空掘巷的稳定性,提出“锚杆+锚索+W钢带+钢筋网+工字钢棚”联合支护方案,现场应用结果表明,巷道围岩变形量及锚杆索受力均在可控范围内,效果良好。By analysis of the observation results of the roof surrounding rock in gob-side roadway of 4317 isolated-island working face in Wangpo Colliery,it is indicated that there are cracks in the shallow part and good integrity in the deep part of the roof surrounding rock.In order to enhance the stability of 4317 isolated-island working face,a combined support scheme of"anchor rod,anchor cable,W steel belt,steel mesh and I-shaped steel shed"is proposed,whose on-site application results show that the deformation of the surrounding rock and the force of the anchor rod are within a controllable range with good effect.
