摘要
本文以皖北煤电集团公司任楼煤矿7216S炮采工作面推垮型冒顶为例,从孤岛式工作面的底板、顶板岩性特征、煤岩体赋存、支护状况以及推垮特点等方面进行分析,找出薄顶软底厚煤层孤岛式工作面在跟顶开采时,推垮型冒顶的原因及防治对策。
Pushing prop over induced by main roof falling is a common issue encountered in insular coal face. Only taking 7216S coal face in Renlou coalmine for instance, in terms of analysis on rock character of roof & floor, presence of surrounding strata, status of coal-face-brace, peculiarity of main roof falling, and so on, is the aim to find the causes and solvable ways of pushing prop over induced by main roof falling in thick seam with thin roof and soft floor, when insular blasting-coal-face carry forward in roof brushing working.
