摘要
该文采用有限元分析的方法,对某煤矿的巷道围岩应力进行了分析评价,确定了开采巷道所适用的支护方案,为该煤矿其它巷道的顶板管理提供了依据。
Based on the analysis of a mine roadway rock stress and the finite element, through the exploitation model, respectively tensile stress on the roof and roof pillar and shear failure analysis, this paper determined the applicable mining roadway support system for the mine to explore other roadway roof to provide a basis for management .
