极近距离煤层开采巷道合理位置布置与支护效果分析

Analysis on the Reasonable Position Layout and Support Effect of Mining Roadway in Very Close Coal Seam

针对西坡矿极近距离煤层回采期间巷道围岩变形严重的问题,采用理论计算与数值模拟,对下煤层巷道合理布置位置及支护进行研究,并提出与之相匹配的锚网钢带配合矿工钢棚的联合支护方案,为该矿的安全,高效生产提供了借鉴和参考。

In view of the serious deformation of the surrounding rock of the roadway during the mining of the very close coal seam in Xipo Mine,the rational layout and support of the roadway in the lower coal seam are studied by theoretical calculation and numerical simulation,and the matching joint support scheme of the anchor mesh steel belt and the miner's steel shed is proposed,which provides a reference for the safe and efficient production of the mine.
