摘　　要：红庙煤矿为典型的软岩矿井,采动影响、水化作用及其水平应力等因素的综合作用增加了巷道支护的难度。利用FLAC3D数值软件模拟分析软岩巷道的变形规律,分析了采动、应力分布等情况对巷道变形规律的影响,为巷道的设计及支护方案的选择提供了依据。Hongmiao coal mine is a typical soft rock mine. In this mine, the roadway support is very difficult because such factors as the influence of mining, hydration and horizontal stress, etc.. The deformation law of roadway in soft rock was simulated by FLAC^3D, and the effects of mining and stress distribution on the deformation of roadway were analyzed. The results provided a basis for roadway design and selection of supporting system.
