西河煤业3^#煤复采技术探索与实践

Research and Practice of Repeated Mining Technology of 3^# Coal Seam in Xihe Coal Mine

合理开采利用煤炭资源具有深远影响,针对西河煤业3#资源枯竭,考虑到15#煤层投产时间长,含S量高,为了合理安排采掘衔接工作,提出3#煤层资源复采方案,通过技术经济论证,提高了煤炭资源回收率,缓解了采掘接替紧张的矛盾,延长了矿井服务年限,创造了社会经济效益。

Rational exploitation and utilization of coal resources is of far-reaching impacts.Because the 3#resource of Xihe Coal Mine is depleted,the 15#coal seam has been mined for a long time and is of high sulfur content,in order to arrange the convergence work of extraction and mining rationally,the repeated mining program of 3#coal seam is presented,which has improved the recovery rate of coal resources,eased the contradiction of tense convergence of extraction and mining,extended the service life of the mine,and created economic and social benefits after technical and economic evaluation.
