摘　　要：断层破碎带的存在严重影响了综采工作面快速、连续、安全推进。利用FLAC^(3D)软件对活鸡兔矿井综采工作面过断层破碎带期间的顶板矿压和围岩的位移、应力规律进行数值模拟研究,表明工作面过断层期间断层的下盘要比上盘稳定,在断层破碎带更易产生顶板冒落事故,从而为过断层时采取更为合理的安全技术措施提供一定的参考。The exist of fault fracture zone has seriously affected the fast,continuous and safe advancing of fully-mechanized working face. FLAC^（3D）software was used to simulate and analyze the process of the fault zone in the fully-mechanized working face. The development process and the distribution law of the stress field and the displacement were revealed. The analysis found that the fault footwall to be more stable than that of the hanging wall,and it is inclined to appear roof falling accidents in fault fracture zone. These conclusions can provide some reference for applying more reasonable countermeasures when the working face passing through faults.
