矿井工作面巷道布置与采煤工艺的研究

Research of Mine Face of Roadway Layout and Coal Mining Technology

以高河矿W2307工作面回采3号煤层为研究对象,通过介绍周边地质、水文等环境情况,针对工作面特殊的地质情况,选择了巷道支护的选型,并对其强度进行了验证计算,在此基础上结合巷道管理的注意事项,制定了合理的采煤方法和采煤工艺,不仅为高河矿3号煤层安全生产提供了技术支持,更为以后类似煤矿的开采提供了参考依据。

Taking W2307 Gaohe mining face in NO.3 coal seam as the research object,introduced the surrounding geology,hydrology and other environment conditions,accorded to the geological situation of working face special,chose the roadway support in the selection,and the strength theory verification,this paper expounded the matters needing attention of roadway management,so as to make the reasonable mining method and mining process,not only for Gaohe mine NO.3 coal seam in provide the technical support for safety production,more be used as reference for similar coal mining in the future.
