This work presents a multi-objective optimization approach to designing integrated water supply systems for the mining industry. The main goal is to estimate the total operational costs and greenhouse gas emissions from water supply systems. Chilean mining industry has been selected as a case study because of acute problem of water scarcity that it experiences. The current strategy to face the problem applied by the mining companies operating in Chile consists in building independent water supply systems that use ocean as the source of water. This solution is highly energy intensive, which is why the problem of water consumption is also a problem of energy consumption. The proposed optimization approach determines - from technical, economic and environmental perspective - the optimal topology of the system, optimal locations and sizes of water treatment plants, pumping stations, and pipelines. In addition, the analysis takes into account the eventual use of photovoltaic solar system in order to decrease greenhouse gas emissions. Our main findings have demonstrated that an integrated water supply system is always the best option from an economic and environmental point of view.

在设计采矿业的供水系统中应用多目标优化方法。智利的情况
这项工作提出了一种多目标的优化方法,以设计用于采矿业的集成供水系统。主要目标是估算供水系统的总运营成本和温室气体排放量。智利采矿业因遇到水资源短缺的严重问题而被选为案例研究。面对在智利运营的矿业公司所应用的问题,当前的策略是建立独立的供水系统,该系统使用海洋作为水源。该解决方案是高能耗的,这就是为什么水消耗问题也是能量消耗问题的原因。拟议的优化方法从技术,经济和环境的角度确定了系统的最佳拓扑,水处理厂,泵站和管道的最佳位置和大小。此外,分析还考虑了最终使用光伏太阳能系统以减少温室气体排放的可能性。我们的主要发现表明,从经济和环境角度来看,集成供水系统始终是最佳选择。
