摘　　要：以五沟煤矿F16断层的地质条件为背景,采用三维有限差分数值软件FLAC3D的固液耦合模式,对断层倾角、断层破碎带宽度及承压水水压不同时,在断层上盘煤层开采过程中断层界面滑移量的变化规律进行了分析,研究得出:断层界面同一标高处的垂向滑移量随断层倾角、断层破碎带宽度及含水层水压的增加而增大。断层界面的垂向滑移量越大,突水危险性越大。The study was on the geological conditions of F16 fault of Wugou coalmine, using solid-liquid coupling model of 3D finite difference numerical software FLAC^3D. Analysis was made on variation of interface slip of fault during the process of coal mining on the interface when width of fault fracture zone, the fault dip and confined water pressure were different. The research conclusion is that the vertical slip at the same elevation of fauh interface in creases with the growth of fault dip, width of fault fracture and aquifer water pressure. The more the vertical slip amount of interface, the higher risk of water inrush is of.
