摘　　要：为了研究赵家寨煤矿综采工作面断层对底板突水的影响,根据工作面水文地质条件和岩石力学性能等参数,运用岩石破裂过程分析软件RFPA2D-Flow,模拟不同倾角的正断层在采动影响下工作面底板的裂隙变化规律。模拟结果在一定程度上揭示了断层倾角对底板突水的影响规律。模拟结果表明,断层倾角越小,断层越容易活化与突水。In order to study the impact of the fault in fully mechanized mining face on floor water inrush in Zhaojiazhai Mine, according to the hydro-geological conditions and rock mechani- cal properties and other parameters in the face, the rock failure process analysis software-RF- PAgD-Flow is used to simulate the floor crack changing law under normal faults with different dips during mining. To a certain extent, the simulation result reveals the impact rule of fault dip on water inrush in face floor. The result shows that the fault with smaller dip angle is more easily activated to induce water inrush in coal floor.
