摘　　要：为优化三山岛金矿西山深部北区上向进路充填采矿法的采场结构参数,基于矿体的开采技术条件,初步选择了10种采场结构参数,利用ABAQUS软件对10种采场结构参数进行数值模拟分析,再结合模糊数学方法对10种模拟结果进行优化。经过综合对比分析,推荐方案2作为三山岛金矿西山深部北区SL06154盘区采场的结构参数,即一步进路采场宽度8 m,二步进路采场宽度6 m,进路采高4.5 m,采用隔一采一的方式。Based on the mining technical conditions of the orebody in the north area deep in Xishan area of Sanshandao Gold Mine,this study aims to optimize the stope structural parameters for the upward approach cut-and-fill mining method.10 preliminary stope structural parameters were selected and analyzed using ABAQUS software for numerical simulation.These simulation results were further optimized using fuzzy mathematics.Through comprehensive comparison and analysis,Scheme 2 is recommended for the structural parameters of the stope in the SL06154 panel of the north area deep in Xishan area of Sanshandao Gold Mine.The scheme involves a first-step stope width of 8 m,a second-step stope width of 6 m,and a stope height of 4.5 m,with an alternate mining approach for the orebody in the north area deep in Xishan area of Sanshandao Gold Mine.
