摘　　要：以西石门铁矿堑沟底部结构诱导冒落法开采边角残留矿体为背景,对堑沟回采矿石量、金属量、品位等指标进行计算,建立了以采出金属量和采出品位为目标的多目标最优化数学模型.结合残矿开采实际情况,选择采出金属量作为最优化问题的主要目标.利用TCL脚本语言对SURPAC软件进行二次开发,并应用其对最优化问题约束条件下堑沟底部结构空间位置的可行方案进行全因子实验.最后得出采切工程布置的最优方案为:堑沟底部结构位于103.1 m水平,与矿体间距为18.65 m.较原设计方案,最优方案采出金属量提高27.79%.This article aims at caving corner residual orebody by trench bottom structure in Xishimen Iron Mine. SURPAC software was used to calculate the ore volume,amount of metal and grade. A mathematical model of multi-objective optimization was established to maximize the amount of metal and grade. According to the special situation of corner residual orebody mining,the amount of metal was selected to be the main object. SURPAC software was developed to automatically calculate by using TCL script. With the help of the script software,all factors in the constraint were tested. The optimum position of trench bottom structure was obtained,which is on the 103. 1 m level and 18. 65 m to the orebody. Compared with the original design,the amount of metal is increased by27. 79% after this optimal design.
