摘要
过高冒空巷回采是综采工作面一个常见问题,也是工作面顶板管理的一个难题。王庄煤矿通过提前对高冒空巷的注超高水材料充填加固,过空巷前的工作面调斜和上漂沿顶回采,以及过空巷期间的快速生产组织、顶板超前管理等综合管理方法,保证了工作面安全顺利过高冒旧切眼回采。
It＇s a common problem that the high risk empty roadway and mechanized mining face roof management for mechanized caving face. It improved integrated management methods of ultra - high - water material filling reinforcement in advance, and working face roll steering and climbing along roof recovery before passage roadway, as well as rapid organization of production during the period of passing empty lane, and integrated management methods of roof advanced management and so on, and approach to ensure a smooth working of surface recovery in Wangzhuang Coal Mine.
