摘　　要：为解决高应力破碎围岩条件下单轨吊悬吊问题,根据实际应用环境,进行围岩锚固性试验,探讨了悬吊结构中锚杆受力状况,分析了锚杆悬吊技术的可行性,借助有限差分数值计算程序FLAC,模拟研究了悬吊载荷对巷道围岩应力分布和变形影响,结果表明,悬吊结构对巷道变形和稳定性影响极小;根据N2202工作面回风巷和胶带巷顶板条件,设计采用双高强锚杆进行单轨吊悬吊,将悬吊结构安装在井下巷道中。通过运输液压支架检验其合理性和可靠性,结果表明高强锚杆悬吊技术能够完全满足矿井使用。In order to solve the problem of monorail suspension under the high stress and broken wall rock conditions , according to un- derground application environment , surrounding rock anchorage experimentation is done and bolt force is explored in the suspension structure, the technical feasibility of the bolt suspension is analyzed, with the help of finite numerical simulation soft FLAC, the sur- rounding stress distribution and rock deformation caused by suspension loads is studied thought the numerical simulation , the results show that the suspension structure load has a little effect on the deformation and stability of roadway; According to the roof conditions of No. S2106 return and convey lane, the double strong bolt is designed to suspend monorail, and the suspension structure is installed in the underground tunnels, the rationality and reliability are tested through the conveying hydraulic support, the results show that double strong bolt suspension monorail technology can satisfy mine use.
