摘要
实现对边角煤的有效利用不仅能提升矿井煤炭资源整体回收率,还能增加矿井综合收益,为矿井长久发展提供坚实保障。针对下边角煤开采工艺开展探究分析,分别对边角煤回采面巷道布置方式与采掘工艺及支护工艺做出总结分析,希望能为其他矿井边角煤的有效回采提供指导和依据,推动矿井资源利用率的显著提升。
The effective use of the corner coal can not only improve the overall recovery rate of coal resources in the mine,but also increase the comprehensive income of the mine and provide a solid guarantee for the long-term development of the mine.Based on the exploration and analysis of the mining technology of the lower corner coal,this paper summarized and analyzed the roadway layout,mining technology and support technology of the corner coal mining face,hoping to provide guidance and basis for the effective mining of corner coal in other mines and promote the significant increase in resource utilization of mines.
