摘　　要：为了寻求某矿-340m以下矿体回采的合理结构参数,采用FLAC3D有限差分软件,建立采场结构模型,对矿体的回采进行模拟。运用正交试验的特性分析了不同尺寸的矿房宽度、间柱宽度、顶柱厚度、分层高度在矿房回采后对矿柱安全系数与位移的影响,并最终确定最佳的采场结构参数为阶段高度70m,矿房宽度8m,间柱宽度8m,顶柱厚度8m,底柱厚度6m,分层高度4m。A mining process is simulated by building a structure model of stope,using FLAC3 Dfinite difference software to seek the reasonable structure parameters of a mine under the level of-340 m.The different size width of stope and pillar width,top pillar thickness,layer height influence on the pillar safety factor and displacement after the stope is mined are analyzed in light of the characteristics of orthogonal test.The optimal stope structure parameters are ultimately determined to be level height of 70 m,of chamber width 8m,pillar width 8 m,top pillar thickness8 m,floor pillar thickness 6mand layer height 4m.
