朱家店煤矿近距离煤层巷道支护技术研究

Research on Roadway Support Technology of Close Distance Coal Seam in Zhujiadian Coal Mine

针对朱家店煤矿近距离煤层巷道支护问题,通过顶底板力学分析等方法,以矿井0407运输顺槽为研究基础,确定了该顺槽掘进过程中巷道支护方案,保证了矿井安全高效回采。通过实践验证:该种支护方案对巷道维护有很好的效果,可以有效的遏制巷道变形问题,为同类型矿井提供了技术基础。

Aiming at the problem of roadway support in close distance coal seam of Zhujiadian coal mine,through the method of roof and floor mechanical analysis,based on the research of 0407 transport gateway,the roadway support scheme in the process of gateway excavation is determined,which ensures the safe and efficient mining of the mine.Through practice verification:this kind of support scheme has a good effect on roadway maintenance,can effectively curb the roadway deformation,and provides a technical basis for the same type of mine.
