摘　　要：为缓解五凤煤矿复合顶板巷道支护的困难局面,通过理论分析、数值模拟,对复合顶板巷道变形破坏机理及相应的支护技术进行了研究,提出了锚喷支护设计方案(破碎段仍采用工字钢加强支护的方式)。数值结果表明,采用上述设计的支护方案,巷道围岩取得了良好的控制效果。In order to deal with the difficult situation of entry support with compound roof in Wufeng Coal Mine,the deformation mechanism and bolting support technique for this compound roof is studied by theoretical analysis and numerical simulation.The anchor bolting support design was pointed out.I-beam strengthening support was still applied at the broken section.The numerical results show that the design of support programs obtained a good control effect for surrounding rock.
