摘　　要：针对赛尔三矿巷道围岩松散、水化风化影响严重的问题,分析了巷道原支护方案存在的问题及影响巷道围岩稳定的主要因素,运用理论分析和数值模拟等手段优化了巷道支护参数,设计了不同围岩条件下的巷道支护方案。现场监测表明,采用优化的支护方案后,巷道表面位移大幅下降,巷道围岩稳定性有了明显提高,巷道支护效果良好。This article analyzes the problems of the original roadway supporting techniques and the main affecting factors of the roadway stability according to the loose,severe hydrating and weathering wall rocks of No.3 coal mine of Saier company, optimizes roadway supporting parameters by using theoretical analysis and numerical simulation,and designs roadway support techniques under different wall rock conditions.The site monitoring shows that the surface displacement of roadway had a significant decline ,the rock stability had been significantly improved after adopting the optimizing supporting techniques.
