摘　　要：根据某煤矿F_2断层实际地质资料,通过相似材料模拟试验的方法对两盘工作面依次回采对断层活化的影响、断层带的应力变化规律及突水路径的形成进行研究,研究结果表明:随工作面的推进,断层界面的垂直向应力呈现先减小后增大的趋势,且同一推进步距时,上盘界面的应力变化量大于断层带的应力变化量,大于下盘界面的应力变化量;两盘煤层中间地带在两盘依次开采过程中均受到影响,其产生活化突水的可能性较大。According to the actual geological data of a coal mine F2 fault, fault effect, through the method of similar material simu-lation test, we study the two planes mining on the fault activation effect, stress variation laws of fault and water inrush path. Theresults show that with the advancing of working face, the fault interface of vertical stress decreases firstly and then increases; inthe same advancing step, the stress variation of upper plane interface is greater than that of the fault zone and footwatl interface;the middle zone of two planes is affected by two planes mining in turn, the possibility of water inrush is in large possibility.
