斜沟煤矿回采工作面收尾贯通技术研究与应用

Research and Application of Closing-through Technology in Mining Face of Xiegou Coal Mine

针对斜沟煤矿23107回采工作面材料巷与皮带巷位于特厚煤层不同层位这一特殊条件下的收尾贯通,采取了以工作面与回撤通道测量剖面标高比对为主,工作面与回撤通道底煤探测厚度对比、回撤通道施工注灰孔导向指示为辅的综合技术措施,三管齐下,确保了工作面高质量快速贯通与收尾回撤工作。

In view of the special condition of material roadway and belt roadway in 23107 mining face of inclined ditch coal mine located in different strata of extra thick coal seam, the comprehensive technical measures are adopted, which are mainly based on the elevation ratio of working face and withdrawal channel measurement section, the thickness comparison of working face and withdrawal channel bottom coal detection and the guidance indication of ash injection hole in withdrawal channel construction.
