摘　　要：为研究近距离煤层下分层回采巷道合理布置问题,以某矿近距离煤层工作面为背景,在现场监测的基础上,采用数值模拟的方法,利用岩土工程计算软件UDEC对不同内错距情况下下分层回采巷道围岩变形进行数值模拟,通过分析得出了不同内错距下的下分层巷道围岩变形规律并确定了10#煤回采巷道合理布置方案。In order to study the problem of reasonable layout of lower slicing roadway in closed coal seams, taking a closed coal seam working face as background, based on the field monitoring, geotechnical numerical simulation software UDEC is used to study the de- furmation of surrounding rock in different internal malposition. Through analysis, the study got the deformation laws of surrounding rock and identified the reasonable layout of 10# coal roadway.
