抚顺老虎台矿是我国发生冲击地压较早、次数较多的矿区之一。文中以地质动力区划方法查明的各级活动断裂为区域构造格架,将老虎台井田简化成由10条断裂带组成的平面弹性模型,编制了应力计算软件。得出了浑河断裂是一条活动断裂,蠕滑活动是其主要活动方式。它的断裂带及与之平行的F_1断层形成的构造应力区对矿区应力状态起主导作用,采动影响是导致该断裂带内构造应力释放、产生冲击地压的诱因的结论。
Fushun Tiger Table Mine is one of the mining areas where the impact pressure is earlier and the frequency is higher in our country. In this paper, the active faults at all levels, identified by the method of geological dynamic zoning, are regional tectonic frameworks, which are simplified into a planar elastic model composed of 10 fault zones and a stress calculation software is prepared. It is concluded that Hunhe fault is an active fault and creep activity is the main activity mode. The tectonic stress zone formed by its fault zone and parallel F_1 fault plays a leading role in the stress state of mining area. The mining effect is the inducement of tectonic stress release and rock burst in the fault zone.
