摘要
集贤煤矿16层煤由于煤层复合顶板维护困难,采16层煤时复合顶板随采随冒落。解决16层煤开采的问题已刻不容缓。托复合顶板开采不但经济效益明显,同时实现了安全生产,减少了矸石排放所带来的环境污染,解决了后续开采的技术难题。
Due to maintenance difficulties of the complex roof in NO.16 coal seam in Jixian Coal Mine,the complex roof caved with mining.Solving the mining problems in NO.16 coal seam is imperative.Mining with supporting the complex roof not only has effective economic benifist,but also realizes safety in production,reduces the environmental pollution caused by waste rocks emission,solves the technical problems in the follow-up exploration.
