摘　　要：根据陈四楼煤矿现场取断层带岩样,进行了断层岩样长期蠕变物理力学试验,得到了断层岩样的实验室数据。运用FLAC数值计算软件,对陈四楼煤矿底板断层进行渗流耦合模拟以及渗流蠕变分析研究。根据研究结果推导出断层带内不同深度处孔隙水压随采场推进距离的经验公式,为煤矿的断层防治水提供了理论依据。According to take fault rock in Chensilou coal mine, the fault creep for physical and mechnical tests of rock samples obtained fault rock sample laboratory data. Using FLAC numerical simulation software, bottom of chensilou coal mine to coupling fault simulation and study on seepage analysis of creep. Based on the results derived at different depths within the fault zone pore water pressure with the empirical formula of stope drive-up, provides theoretical basis for fault prevention of the mine water.
