摘要
针对荣泰矿综采工作面坚硬的顶板条件,结合工作面末采工艺,分析了综采工作面顶板压力与垮落情况,提出针对坚硬分层顶板末采支护方案。结果表明:该方案不仅为实现快速拆除创造良好条件,缩短末采扩帮到设备拆除时间,同时实现了降本增效,具有较强的推广价值。
In view of the rong tai mine hard roof conditions in fully mechanized working face, combining with the face at the end of the mining process, the roof pressure of fully mechanized working face with caving was analyzed, the strong layered roof support scheme was proposed, the experiment was a success, not only created a good condition in order to achieve rapid demolition, shortened the mining expansion in terminal mining, at the same time achieved cost decreasing and benefit increasing, with a strong promotional value.
