摘　　要：传统矿山短期生产计划优化研究围绕经济和生产指标,忽视了矿山固废处置的环境影响。生产计划和进度直接决定充填过程和尾砂消耗,进而影响其他尾砂处置策略。本文提出了一个采充协同作用下的矿山短期计划优化模型,添加了充填尾砂消耗限制,将充填尾砂消耗量波动最小设定为优化目标。最终实现了采矿和充填计划的联合优化。结果表明:相比传统模式,该模型每月可减少尾砂堆存量超过30%,降低了尾砂对环境的损害,提升了尾砂绿色处置比例。同时,模型输出的出矿量和品位波动满足矿山生产要求。Traditional researches on optimizing short-term mine production schedules often focus on economic and production metrics,neglecting the environmental impact of mine waste management.Production schedules directly determine the backfilling processes and tailings consumption,thereby influencing other tailings disposal strategies.This paper proposed a short-term mine planning optimization model under mining-backfilling coordination,incorporating backfill tailings consumption constraints.The minimization of fluctuation in backfill tailings consumption was set as the optimization objective.The model ultimately achieved joint optimization of mining and backfilling schedules.The results show that,compared to traditional methods,the model can reduce monthly tailings storage by over 30%,minimizing environmental impact from tailings while increasing the proportion of green tailings disposal.Meanwhile,the model’s output of extracted ore tonnage and grade fluctuations meet the mine’s production requirements.
