摘　　要：近距离下分层回采巷道布置形式决定了在整个掘进、回采期间巷道支护的难易程度。将巷道布置在煤柱下方的低应力区是实现控制巷道稳定性的根本途径。本文阐述了下分层回采巷道的布置类型,提出了近距离下分层回采巷道的合理布置形式,并以高阳矿下分层工作面巷道的布置为例,分析了该矿102、902和104工作面的布置方式,总结了应力集中区施工的注意事项,可为同类型条件回采巷道的布置提供参考。The difficulty of roadway support during tunnelling and mining is decided by the layout form of close distance coal seam lower slicing mining roadway.The roadway is arranged on the low stress zone under coal pillar,which is the basic solution of realizing control the roadway stability.This paper expounds the layout type of lower slicing roadway,puts forward the reasonable layout type of close distance lower slicing mining roadway,and takes Gaoyang coal mine for example,analyzes the layout form of 102,902 and 104 working face,summarizes the matters needing attention of construction in areaes of stress concentration,it can provide a reference for the layout of mining roadway in similar conditions.
