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。
In order to study the influence of connectivity, development height and spatial distribution of hidden faults on the water inrush process of buried faults, according to the actual engineering geological conditions in Dongjiahe coal mine, three simplified models are established, and RFPA-Flow finite element software The hidden faults of the bottom plate are simulated, under the common action of mining stress disturbance and confined pressure water, to activate, expand and pierce the whole process. The results can provide reference for the prediction of water inrush accidents caused by confined water mining.
