摘　　要：矿井进入深部资源开采阶段时,会出现地应力大、支护难度大的问题。以钱营孜煤矿一条暗斜井为例,通过对巷道支护设计方法的分析,设计出巷道支护方案,并提出采用相关监测方法对巷道支护效果进行检验,利用巷道监测反馈结果来验证支护方案。此循环性支护设计方法能有效控制围岩变形,达到巷道支护设计效果。When the mine enters the stage of deep resource exploitation,there are problems of large in-situstress and high difficulty in supporting.Taking an inclined roadway in Qianyingzi Coal Mine as an example,through the analysis of the roadway support design method,the roadway support scheme was designed,and the relevant roadway support detection method was put forward to test the roadway support effect.The results showed that the cyclic support scheme can effectively control the deformation of the surrounding rock and achieve the effect of roadway support design.
