摘要
近年来,矿区推行大规模机械化、集约化生产方式,加大了矿井开采强度,提高了矿井生产水平。但是,正规生产、切块布置方式之后遗留下大量边角煤开采及资源回收问题亟待解决。针对边角煤的开采现状,为提高煤炭资源回收率,延长矿井寿命,迫切需要提出一套高回收率和高效率的边角煤开采工艺。
In recent years, coal mining carried out large -scale mechaniztion and intensive produc- tion way. It has raised the mine production level. But massive comer coal remained and the resource re- covery question urgently awaited to be solved. To raise coal recovery ratio and extend mine life, a high recovery -ratios and high efficiency comer coal mining technique is urgently needed.
