摘要
针对创日泊里煤矿生产中出现的工作面突水问题,从理论层面上分析了其发生原因,建立了断层影响下的工作面底板力学模型对其进行受力分析。采用RFPA2D-Flow软件建立了断层工作面的数值模型,通过模拟不同断层倾角以及正逆断层对工作面底板突水情况,得出不同断层对突水情况的影响。
Aiming at the problem of water inrush in coal mine production, the reason of the occurrence is analyzed from the theoretical level, and the mechanical model of the face plate under the infuence of fault is established. The numerical model of fault face was established by RFPA2D-Flow software. The infuence of different faults on the water inrush was obtained by simulating the problem of water inrush at the face of the fault.
