摘　　要：为研究隐伏小断层的连通情况、发育高度与空间分布因素对底板隐伏小断层突水过程的影响,根据董家河煤矿实际工程地质条件,建立3种情况简化模型,运用RFPA-Flow有限元软件对煤层底板隐伏小断层在采动应力扰动和承压水共同作用下活化、扩展、贯通的全过程进行模拟。研究结果可为承压水上开采引发的突水事故的预测提供参考。To investigate the process of water inrush related to the concealed small faults of coal floor and the influence of the height of small faults,the spatial location. According to the actual engineering geology, establishes three simplified models,uses the finite element software RFPA-Flow to simulate mining disturbance and pressure water to get the whole process of the small faults activation, extensions.The research results can provide references to the water inrush risk.
