摘　　要：峰峰集团新三矿已进入资源枯竭期,采面多沿采空区及大巷煤柱布置,地质条件复杂,单面储量小,搬家倒面频繁。因此,以工作面切顶卸压自成巷经验为基础,制定162312工作面切顶卸压L型垂直对接连采方案,不仅多回收了煤炭资源,还实现了衔接期间产量稳定,为完成全年产量任务奠定了基础。New No.3 Coal Mine of Fengfeng Group has entered the resource depletion period.The mining faces are mostly arranged along the goaf and the main roadway pillar.The geological conditions are complex,the reserves on one side are small,and the face is moved frequently.Therefore,based on the experience of roof cutting and pressure relief in the working face,the"L"type vertical docking continuous mining scheme for roof cutting and pressure relief in the 162312 working face was developed,which not only recycled more coal resources,but also achieved stable output during the transition period,laying the foundation for completing the output task throughout the year.
