摘　　要：采用有限元模型分析的方法,以兴陶矿的围岩条件建立了数值分析模型,对预应力锚拉支护中安装应力进行了有限元分析计算,从而确定了回采巷道锚拉支护的合理安装拉力。Numerical analysis model was set up by the analytical method of finite element model and according to the conditions of surrounding rock in Xingyan Mine, finite element analysis and calculation were conducted for the erection stress of pre-stress bolt tensioned support, this thus can define the reasonable erection tension of bolt tensioned support in the actual mining roadway

关 键 词：锚拉支护 有限元 安装预拉力 兴陶矿 围岩条件
