摘　　要：断层在井工煤矿采掘工作中极为常见,周期来压也是常见的矿压显现过程,当工作面同时面临过断层及周期来压时,就有可能造成严重的冒顶片帮事故,威胁安全生产。以汾西矿业集团中兴煤矿2208工作面为工程背景,综合运用现场调研、理论分析及文献查阅等研究方法,对工作面典型顶板事故进行调研,分析冒顶片帮的原因及处理难点,进而设计了马丽散注浆加固方案,并成功用于工程实践,实现了预期的安全及技术目的。Faults are very common in the mining work of underground coal mines,and periodic pressure is also a common process of ground pressure appearance.When the working face is faced with faults and periodic pressure at the same time,it is likely to cause serious roof fall and wall fall accidents,threatening safety production.Taking the 2208 working face of Fenxi Mining Group Zhongxing Coal Mine as the engineering background,the typical roof accidents of the working face are investigated by comprehensively using the research methods of on-site investigation,theoretical analysis and literature review,and the causes and treatment difficulties of roof falling and spalling are analyzed.Then,the Malisan grouting reinforcement scheme is designed and successfully used in engineering practice to achieve the expected safety and technical purposes.
