摘要
文章以阳煤五矿胶带运输巷和调车线两相交巷道交叉点为工程背景,利用ANSYS软件计算分析了不同交叉角度顶底板应力分布情况及位移变化规律。研究结果表明:巷道交叉点处锐角三角区域和钝角三角区域围岩角度的比值是判定巷道围岩稳定性的一个重要因素;同时,两者的比值还是判定巷道交叉点围岩应力集中程度的一个重要指标。
Based on a belt transportation roadway and an intersection of a shunting line two intersection roadway in Yangquan No. 5 Mine as an engineering background,an ANSYS software was applied to calculate and analyze the different cross angle roof and floor stress distribution law and displacement variation law. The study results showed that a special value of the surrounding rock angle in the acute triangle area and the obtuse triangle area at the intersection of the mine roadway was an important factor to judge the surrounding rock stability of the mine roadway. Meanwhile,the special value of the two angles also would be an important index to judge the stress concentration degree of the surrounding rock at the intersection of the mine roadway.
