摘　　要：重点介绍FLAC3D数值模拟法在煤炭开采过程中引发断层活化及导水机理的研究,该方法适用于开采煤层受断层对盘存在承压含水层影响的情况。在可能出现断层导水引发溃水事故的情况下,采用该法科学掌握断层活化导水机理,在合理留设防隔水煤柱方面取得了较好的效果。Focuses on the study of fault activation and water conduction mechanism induced by FLAC3D numerical simulation method in coal mining process. This method is suitable for mining coal seams affected by faults on the existence of confined aquifers in the wall. In the case of water burst accident caused by fault water conduction, better results have been achieved by using this method to scientifically grasp the mechanism of fault activation water conduction and reasonably retain water-proof coal pillars.
