水力采煤在三家子矿的应用与发展

Application and Development of Hydraulic Coal Mining at Sanjiazi Coal Mine

本文介绍了南票矿务局三家子矿井田地质和矿井概况，采煤方法的更迭和最后水力采煤方法在该矿的应用。在生产实践中该矿对巷道布置、高压水供水方式、硬煤开采、煤泥回收、设备的合理使用、节能降耗等各工艺环节不断改进，取得了明显效果，并提出今后发展的努力方向。

To suit the geological conditions of the mine, the hy-draulic coal mining method is finally adopted to replace theconventional mining methods previously employed. In practicaloperation rcmarked result has been obtained through incessantimprovement of Layout of headings, high - pressure watersupply system, mining of hard coal, recovery of coal slurry, ra-tional use of facilities, and cutdown of energy and materialsconsumption. At last the paper Points out the orientation forits further development.
