以贵州某煤矿沿空留巷巷道为研究对象,采用RFPA数值模拟软件建立数学模型,对该沿空留巷巷道在目前支护条件下的围岩变形破坏情况进行了数值模拟分析,得出该巷道靠采空区一侧及靠煤帮底角稳定性较差的围岩变形破坏规律,为该矿井针对性地加强沿空留巷巷道支护提供依据。 Taking mine gob-side entryway in a coal mine in Guizhou as the research object, the mathematical model was established by RFPA numerical simulation software, and the numerical simulation analysis of surrounding rock deformation and gully of gob-side entryway under the condition of current support was given. The law of surrounding rock deformation and failure of the roadway on the side of the gob and the poor stability of the bottom corner of coal seam provided the basis for the mine to strengthen the support of gob-side entry retaining lane.
