| 摘 要： | 以塘冲煤矿为工程背景,通过数值计算和现场实测,分析了断层的活化对采空区导水裂隙带高度的影响.在工作面超前支承压力的作用下,工作面前方断层活化,改交了采场应力场和岩体运动规律,导致导水裂隙带高度增加,从而破坏隔水层导通上覆承压岩溶含水层,引发矿井突水事故.

| Abstract: | Taking Tang Chong coal mine as project background, influence of fault activation on height of water flowing fractured zone was analyzed by numerical computation and field measurement. Under the front abutment pressure, for the front of face's fault activation, the stress field in stope and the movement law of rock was changed, that lead to the height of water flowing fractured zone increasing, the karst aquifer was got through because aquifuge was failure, so water inrush accident was occurred. |
