摘要
针对放顶煤开采煤炭损失大的问题,从地质赋存与开采技术两方面分析了其关键影响因素,提出提高煤炭回收率应从合理选择放顶煤支架、确定合理的放煤工艺和放煤步距、加强工作面管理三方面入手。
According to the problems of big loss in top coal caving, this paper analyzed its key influence factors from the aspects of geological occurrence and mining technology, and proposed that reasonable selection of caving supporting, ensuring reasonable coal technology and coal drawing interval, and strengthening working face management can improve coal recovery.
