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 reasonable arrangement of roadway in stratified mining under short distance coal seam, based on the working face of a short distance coal seam in a mine and on the basis of on-site monitoring, a numerical simulation method is used to calculate the influence of different internal displacement The surrounding rock deformation of the lower stratified mining roadway is numerically simulated, the deformation law of the surrounding rock of the lower stratified roadway under different internal clearances is obtained and the rational layout scheme of the 10 # coal mining roadway is determined.
