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%.
Based on the background of the residual ore body at the edge of the ground where the bottom structure of the Shigou iron ore trench is induced to lead the mining, the ore amount, metal content and grade of the ore dug in the trench are calculated. Based on the actual situation of the residual ore mining, the main objective of the optimization is to choose the metal quantity as the main objective of the optimization.Using the TCL scripting language to develop the SURPAC software for the second time and to apply it to the optimization problem constraints Through the full factorial experiment, the feasible scheme for the spatial structure of the bottom of the trenches was obtained.Finally, the optimal scheme of cutting and layout was obtained: the bottom structure of the trenches was located at the level of 103.1 m and the distance to the ore body was 18.65 m The excellent plan mining volume increased 27.79%.
