摘　　要：为解决和降低冲击地压事故对矿井安全生产带来的危险,以抚顺老虎台矿区为研究对象,对老虎台矿区的活动断裂进行深入的研究.采用地质动力区划的方法,通过应用地形测量图,并且结合卫星照片、地震震源分布图等,查明了老虎台矿区的Ⅰ~Ⅴ级活动断裂,确定了研究区域内的活动断裂,并且划分出了区域内断块结构.由各级活动断裂所划分出的断块结构表明了老虎台矿区现今构造运动的情况.通过现场考察,结合理论计算的方法明确了活动断裂对老虎台矿区冲击地压有较大的影响.同时分析了断裂构造与区域地震的分布以及活动断裂对冲击地压和矿震的影响.In order to solve and reduce the impact on mine safety production caused by accident of rock burst, this paper took Fushun mining area as the research object, and studied the active fault of Laohutai mining area in-depth. Using the method of geological dynamic division, applying topographic map, and combining with the satellite photos and distribution map of seismic source et al, found out theⅠ~Ⅴ grade active faults of Laohutai mining, this study determined the active faults in the study area, and divided block structure in the area. The block structure divided by all grades active faults shows the present situation of tectonic movement of Laohutai mining area. Spot investigation and combination with the method of theoretical calculation make it clear that the active faults have greater effect on rock burst in Laohutai mining area. At the same time, this study analyzed the distribution of fault structure and regional earthquakes and active faults impact on rock burst and mine earthquake.
