摘　　要：大采高工作面回采期间,在仰采条件下极易遇到顶帮破碎、片帮、冒顶事故,在大采高工作面设计时,尽量避免仰采布置。东庞矿2612、邢东矿2222两个工作面先后遇到上述状况,在回采前期,顶板破碎、片帮、超高对工作面产生较大影响,后期通过锚索加固、注浆加固等一系列措施,改善了煤壁与顶板的力学性质,保证了顶帮完整,为大采高工作面安全顺利回采提供了有利的条件,为矿井高产高效提供了一项实用技术。During stoping in large height mining working face, broken roof side, rib spalling and roof fall are prone to happen under overhand mining, overhand mining should be avoided in the design of large height working face. 2612 working face in Dongpang Mine and 2222 working face in Xingdong Mine with the problem above, broken roof, rib spalling, over height affected working face in early stage of stoping, anchor reinforcement and grouting reinforcement were adopted, which improved the mechanical properties of coal wall and roof, ensured the complete of roof side, provided advantages for large height mining working face stoping and technology to achieve efficient and effective production.

关 键 词：大采高工作面 仰采 顶帮控制
