摘要
介绍了肥城矿区煤层开采情况,分析了煤层赋存现状,研究了8,9,10煤层采空区上方7煤层开采的可行性,对于提高资源枯竭矿井的煤炭资源回收率,延长矿井的服务年限,稳定矿区的生产生活具有重要意义。
In this paper, mining situation of coal strata in Feicheng mining area has been introduced, pres- ent occurrence situation of coal strata have been analyzed, and exploration feasibility of No. 7 layer in mined - out areas of No. 8, No. 9 and No. 10 coal strata have been studied. It has important significant for the improving recovery rate of resource depletion mines, prolonging the service life of mine, and stable production and life in this area.
