摘要
综放工作面在回采时,受锚索锚固力作用,风运巷老塘不能随回采推进而跟进塌落,给顶板管理和瓦斯煤尘管理带来极大隐患。结合现场,将利用退锚索机对端头(尾)空档里帮侧锚索进行退锚放顶,从根本上解决了进风区、老塘、采空区、回风区的锚锁支护顶板快速放顶,不但有效地管理顶板和瓦斯煤尘,而且降低了材料消耗,节约了支护成本,排除了安全隐患。
In actual mining, wnder the grie of anchor line, airdrift used to care becanse of failurt to follow. This situation cansde great troubles to crest slab protection and gassy seam management. This paper intouded a mathod combining the scene to use the mahine in the title to control the tip, basically solving the problems of blasting down the roof in inletair area, minedout space, returnair area. This method not only effectively managed the slab and gassy seam, but reduced materials consccmpfion, saved costs and ruled out potential safety hazard as well.
