本文利用非线性有限元分析方法 ,对上分层煤体回采进行了模拟 ,得出了煤柱宽度对内错式下分层回采巷道合理布置位置的影响规律
In this paper, the non-linear finite element analysis method is used to simulate the upper stratified coal mining, and the influence of coal pillar width on the reasonable layout position of the lower stratified mining gateway is obtained.
