摘　　要：为进一步解决当前巷道掘进效率与工作面回采、支护等能力不相匹配的问题,在对煤矿快速掘进工艺研究的基础上,对蛇形、回形以及螺旋形等五种不同切割路线对应的巷道变形情况进行仿真对比的情况下得出适用于本工程的最佳切割路线;对不同空顶距下对应的工作面巷道顶板、两帮以及底板的变形以及塑性区域分布情况进行对比,得出最佳空顶距为4 m。以上结论均可指导实践生产。In order to further solve the problem of mismatch between the current efficiency of tunnel excavation and the ability of working face mining,support,etc.,based on the research of rapid excavation technology in coal mines,the deformation of tunnels corresponding to five different cutting routes,including snake,loop,and spiral,was simulated and compared to obtain the optimal cutting route suitable for this project.Comparing the deformation and plastic zone distribution of the roof,two sides,and bottom plate of the working face roadway corresponding to different roof spacing,the optimal roof spacing is determined to be 4 meters.The above conclusions can guide practical production.
