摘　　要：以某矿区煤层大倾角工作面复合顶板的开采状况为例,探讨大倾角工作面复合顶板出现冒顶的原因以及相应的处理措施,总结出一套切实可行的处理冒顶事故的系统方案,通过对工作面进行强化质量管理,超前使用锚杆加固煤壁,注射煤体固化剂等措施,实现大倾角工作面复合顶板的安全开采。Taking mining situation as an example,the reason for roof of composite roof on working face with large inclined angle of a mining area faalling of composite roof and relevant countermeasures were discussed in the paper,a set of feasible scheme for processing accidents were summed up.By strengthening quality management of the working face, reinforce the coal wall by using anchor bolt ahead of time, injection of coal firming agent,and so on,the safety mining with composite roof on working face was realized.
