摘 要:文章以红柳煤矿复杂工作面回风巷支护为研究背景,通过现场调研、理论分析等研究手段,提出了2种支护优化方案,借助数值模拟对支护方案进行对比分析。结果表明:工作面回风巷支护优化方案2可以最大限度地减小顶板的位移量,支护效果较好,能够达到煤矿巷道安全支护的需要,同时最大限度地节约材料。The article takes the support of the return air roadway in the complex working face of Hongliu Coal Mine as the research background,through on-site research,theoretical analysis,and other research methods,two support optimization schemes are proposed.Numerical simulation is used to compare and analyze the support schemes.The results showed that the optimized scheme 2 for the return air roadway support in the working face can minimize the displacement amount of the roof to the maximum extent,and the support effect is good.It can meet the needs of safe support in coal mine roadways,and save materials to the maximum extent at the same time.
