摘　　要：本文以洼东煤矿条带开采的地质采矿条件为依据 ,建立了岩体蠕变的粘弹性力学模型 ,确立了其蠕变参数 ,利用 ANSYS的三维立体模型对同一工作面条带开采不同采留宽度条件下的地表下沉和力学效应进行了数值模拟 ,提出了软岩矿井建筑物下条带开采的合理采留宽度 。Based on the geological and mining condition of strip mining of Wadong mine, Viscous Elastic mechanical models of rock mass are established. The parameters of creep are chosen. The surface subsidence and mechanical effect under conditions of various coal pillars width of mining and reservation in strip mining of the same working face is calculated by numeral simulation by ANSYS's three D model, the rational coal pillars width of mining and reservation of strip mining in weak rock mass is brought forward. Scientific reasons are provided for decision makers who carry through mining movement.
