煤峪口矿81010孤岛工作面回采方案研究

Study on Mining Scheme Design of the 81010 Isolated Island Working Face in Meiyukou Coal Mine

同煤集团煤峪口矿为了保证采掘工作面的正常衔接,提高煤炭资源的回收率,对81010孤岛工作面进行了回采。通过对该孤岛工作面条件的分析,采用单一走向长壁后退式采煤方法,对两巷支护进行了设计,制定了回采过程中矿压观测、顶板管理、超前支护等具体措施,顺利进行回采,为同煤集团类似工作面的安全开采提供了指导。

In order to ensure the normal connection of the mining face and improve the recovery rate of coal resources,Meiyukou Coal Mine recovered the 81010 isolated working face.In this paper,through the analysis of the conditions of the isolated island working face,the roadway support,mining,mine pressure monitoring,advance support and so on are designed.According to the design,the mining was smoothly carried out,which provided guidance for the safe mining of similar working faces in Datong Coal Mine Group.
