摘　　要：抽注液量的设计既关乎浸出剂的有效溶浸范围又与井场运行成本有关。为了进行地浸采铀“水平井-直井”抽注系统的经济高效抽注液量决策,提出一种基于多目标优化算法的“水平井-直井”系统抽注液量模拟优化决策方法。研究表明:与均匀布置抽注液量的初始方案相比,决策方案R2的运行成本降低了51.14%,其溶浸范围增加了8.84%。该决策方法筛选出了LK矿区的4口“重点井”,在方案决策及调整时,应重点关注该类井的流量;根据多目标优化的Pareto解集,选取了6组不同有效溶浸范围和成本权重比例的抽注运行方案组合,用以指导决策者进行方案选择。The design of injection and extraction fluid volume is closely related to both the effective leaching range of the lixiviant and the operational cost of the well field.To facilitate economically efficient decision-making regarding injection and extraction fluid volume in the"horizontal well-vertical well"system within the in-situ leaching uranium mining domain,a simulation-based optimization decision method for the"horizontal well-vertical well"system is proposed,leveraging multi-objective optimization algorithms.The research indicate that,compared to the initial scheme of uniformly distributing injection and extraction fluid volume,the decision scheme R2 achieves an 8.84%increase in the leaching range while reducing operational costs by 51.14%.This method has identified four"key wells"in the LK mining area,emphasizing the importance of closely monitoring the flow rates of such wells during scheme decision-making and adjustments.Based on the Pareto solution set derived from the multi-objective optimization,six combinations of injection and extraction operational schemes with varying effective leaching ranges and cost-weight ratios are selected to guide decision-makers in their scheme selection.
