摘　　要：煤矿巷道中锚杆支护方案对煤矿的安全技术具有较大的影响。以某煤矿的不同煤层为研究对象,对原有的支护方案进行分析,针对当前使用方案所存在的问题,提出对支护参数的优化,并以两帮及顶板的变形量为试验依据,最后采用试验的方式对优化方案的可行性进行验证。试验结果表示,采用优化后的支护参数,巷道两帮与顶板的变形量均小于未采用优化方案的变形量,支护效果得到了良好的改善。Anchor rod support schemes in coal mine roadways have a large impact on the safety technology of coal mines. The original support scheme was analysed for different coal seams in a coal mine, and the optimization of the support parameters was proposed to address the problems of the currently used scheme. The test results show that the deformation of the two gangs and the top slab of the roadway with the optimized support parameters is smaller than that without the optimized scheme, and the support effect is improved.
