摘要 深井软岩巷道支护是巷道支护的难题之一。以具体的工程为例,分析认为巷道变形严重是由于深部的高应力和围岩的强流变性。基于此分析,提出了"锚、绳、喷、注"的联合支护技术。实验结果表明,该技术取得了良好的治理效果,巷道围岩变形量明显降低,保证了巷道的正常运行。 Surrounding rock control of compound soft rock roadway was one of difficult problem of roadway supporting. Based on the specific engineering project, the reason of the deformation that the high stress of deep roadway and the strong theology surrounding rock were analyzed, the existing problems of the primary support program was revealed, and a technology that the "bolt, steel wire rope, spray, grout" controlling the surrounding rock was used. The result of the experiment showed that good effect of surrounding rock controlling was obtained and the deformation convergence was small.
