摘要
针对综采工作面过空巷期间出现冒顶压架的问题,以锦瑞煤业8306工作面为背景,对工作面压架原因进行了分析,提出了采用注浆和架木垛处理冒顶区,清理机道、放炮起底后拉架,以及后期预防压架的技术措施,取得了良好效果,为以后处理类似事故和工作面预防压架提供了宝贵经验。
In view of the problem of frame pressing by roof fall in passing abandoned roadway at 8306 fully mechanized working face of Jinrui Coal Industry Co.,the paper introduces the technical measures of handling roof fall area with grouting and frame cribbing,pulling frame after clearing the machine way and pre-blasting,and preventing frame pressing in the later stage,which can provide experience for preventing similar accidents in the future.
