摘要
目前,中国极近距离煤层开采仍然存在诸多不足,尤其是回采巷道布置方面存在着难度较大、巷道布置效果不佳等情况。针对这一实际问题,首先对极近距离煤层的特点及其重要性进行探讨,对极近距离如何确定回采巷道位置和支护方式的选择提出建设性意见,再结合实际案例进行分析实践,为高效开采极近距离煤层以及提高煤炭资源回收率探索出更加科学、合理的执行方案。
At present,there are still many deficiencies in the mining of extremely short-distance coal seams in China.In particular,the layout of the mining roadway is difficult and the roadway layout effect is not good.Aiming at the practical problem,this paper firstly discussed the characteristics and importance of the extremely short-distance coal seams,put forward constructive suggestions are on how to determine the location of mining roadways and the selection of support methods in extremely short distances,and then carried out practical analysis combined with the actual case,in order to explore a more scientific and reasonable implementation plan for efficient mining of extremely short-distance coal seams and improvement of coal resource recovery rate.
