摘要
为了探索7 m大采高综采工作面顶板控制经验,实现7 m大采高工作面的安全高效生产,通过对大柳塔煤矿52303工作面机尾冒顶现场处理,采用理论分析与现场工程实践相结合的方法,分析了冒顶的原因及机理,提出了现场解决方法和预防措施,为矿井安全高效生产提供了技术保障,积累了经验。
To explore the roof control measures and realize the safety and effective production of fully mechanized mining face with 7m large mining height,according to the roof fall accident at tailgate of No. 52303 face of Daliuta Coal Mine,the causes and mechanisms of the roof fall were analyzed by using theoretical analysis and field engineering practice and the solution methods and the precaution measures were proposed. This study provides technical support for the mine safety and efficient production.
