摘要
店坪煤矿通过调整采掘衔接,先行开采下分层9#煤,导致上覆3#煤和5#煤被留置,且局部已形成蹬空区。为进一步提高矿井煤炭资源采出率,减少资源浪费,延长矿井服务年限,本文主要介绍了店坪煤矿工作面基本情况,并设计与监测该煤矿3-3032巷道,反顺序开采3#煤和5#煤,围绕工作面布置存在的问题,通过现场实际试验,提出上分层工作面可靠布置形式及支护方式,为同类型地质条件下矿井积累经验及提供理论依据。
Dianping Coal Mine has adjusted the mining connection by first mining the lower layer of 9#coal,resulting in the retention of the overlying 3#and 5#coal and the formation of a goaf in some areas.In order to further improve the extraction rate of coal resources in the mine,reduce resource waste,and extend the service life of the mine,reverse sequence mining was carried out for 3#and 5#coal.Based on the problems in the layout of the working face,reliable layout and support methods for the upper layered working face were proposed through on-site practical experiments,accumulating experience and providing theoretical basis for mines under similar geological conditions.
