艾芬豪矿业(Ivanhoe Mines )称，其Kakula矿脱水计划的第二阶段已启动，但将推迟发布2026-2027年铜产量指导，待脱水区域完成实地检查后再予公布，此前公司原计划9月中旬发布这两年产量展望及新矿山寿命计划。目前，第二阶段的四台大容量潜水泵中有三台已按计划安装并投入运行，Kakula矿地下水位较原先预计的80米下降约10米。剩余一台泵预计未来几天启用，届时总泵送速度将达到约每秒2600升。之后，他们将根据水位下降情况，将现有的第一阶段临时抽水设施向矿井更深部转移。艾芬豪矿业估计，Kakula矿的总抽水率预计将提升至每秒约6,400升，即每天550兆升，使垂直水位每天降低约一米。预计到11月底地下水位将降至接近第二阶段脱水井底部，从而为进入高品位矿区提供更多通道。根据当前预估，短期内艾芬豪矿业预计随着地下采矿活动的逐步增加，产量将恢复至年超55万吨的水平。Kakula矿是刚果民主共和国Kamoa-Kakula矿综合体的一部分，今年早些时候，因地震活动导致井下严重涌水，该矿被迫停产约三周。停产后，艾芬豪矿业管理团队将2025年的产量预测下调28%，至37万至42万吨精矿铜，同时实施了三阶段排水计划以恢复全面运营。
