摘　　要：为了解决近距离下煤层巷道围岩变形大的问题,利用数值模拟结合理论分析,对下煤层巷道合理布置位置及支护进行研究,通过对下煤层巷道重叠布置、外错布置及内错布置优缺点进行分析,提出内错同向布设方式。通过数值模拟分析,对近距离煤层巷道围岩垂直应力分布情况进行研究,给出了锚网钢带配合及矿工钢棚联合支护方案,经过验证确定了支护方案的可行性。In order to solve the problem of large deformation of the surrounding rock of the near lower coal seam roadway,this paper uses numerical simulation combined with theoretical analysis to study the reasonable layout position and support of the lower coal seam roadway,by analyzing the advantages and disadvantages of the overlapping layout,the outer wrong layout and the inner wrong layout of the lower coal seam roadway,and proposes the inner wrong homogeneous layout.Through numerical simulation analysis,the vertical stress distribution of the surrounding rock in the close coal seam roadway is studied,and the joint support scheme of anchor mesh steel belt coordination and miner’s steel shed is given,and the feasibility of the support scheme is determined after verification.
