摘　　要：针对煤矿软岩巷道围岩变形与破坏问题,通过实验研究,确定了有效控制软岩巷道围岩大变形的合理支护强度。并据此研究结果设计了淮南谢桥煤矿极软岩巷道的支护方案与参数。实践证明,研究结果可靠,应用效果良好。In view of the problem of deformation and damage in eoalmine roadway surrounded by soft rocks, the reasonable supporting strength is determined by testing study to effectively control roadway deformation in soft rocks. Based on these research results, the supporting plan and parameters of roadway in Xieqiao coalmine in Huainan are designed. It has been proved by the practice that the research results are reliable and the practical effects are good.
