摘要
利用数值模拟(ANSYS)对巷道进行分析。对位于底板的巷道和位于顶板的巷道采用半圆拱形支架,分析在矿山压力作用下,对巷道支护后的围岩应力和变形的变化特征,从中寻找巷道变形的规律,对巷道支护具有一定的指导意义。
Using numerical simulation（ANSYS） to analyze the roadway,the semicircle arch support is used in the roadway on the roof and in the floor.The variation characteristics of surrounding rocks and stress after roadway support are analyzed under the action of mine ground pressure.The deformation laws of roadway are obtained.It has some guidance significance to roadway support.
