滚筒式采煤机扩切眼安装工作面的研究与应用

摘要

在综采工作面切眼未扩刷之前，采取先安装综采面正常生产时所使用的滚筒式采煤机和可弯曲式刮板输送机，再通过滚筒式采煤机对切眼巷道进行扩帮刷宽，形成具备综采工作面液压支架安装条件的正常切眼，使工作面的掘进、安装、回采等活动有机的衔接起来，节省了工作面掘进期间扩宽刷大切眼的流程，减少了掘进支护用品及材料的投入，实现了矿井综合效益的最大化。%Before expanding open-off cut in fully mechanized mining face, ifrstly installed the drum shearer and the lfexible scraper conveyor used ifrst fully mechanized mining face during normal production and, then expanded open-off cut by using drum shearer, formed the normal open-off cut which met the hydraulic support installation conditions of fully mechanized working face, made the excavation of open-off cut, installation, mining and other activities organic join, saved time using to widen open-off cut, reduced the investment of support products and materials, and achieved the maximum comprehensive beneift of the mine.
