摘　　要：为降低项目建设和征地成本,缩短项目建设周期,某地浸铀矿山采用准闭路循环系统;与传统地浸采铀矿山相比,准闭路循环系统取消配液池,将集液池改为集液罐。配液泵作为准闭路循环系统的主要动力来源,当其运行不稳定时,易发生冒罐事件,导致循环系统抽注液量不平衡,影响矿区生产进度。通过采用自动化实时监测及优化配液泵调节方式等措施,有效提高了配液泵在地浸采铀准闭路循环系统中的运行稳定性。In order to reduce project construction and land acquisition costs,and shorten the project construction cycle,a in-situ leaching mine adopts a quasi-closed circulation system.Compared with traditional in-situ leaching uranium mines,the liquid distribution tank is cancelled and replaced with a liquid collection tank.As the main power source in the quasi-closed circulation system,the liquid distribution pump is prone to tank overflow when it runs unstable,resulting in imbalanced pumping volume in the circulation system and affecting the production progress of the mining area.By adopting measures such as automated real-time monitoring and optimizing the adjustment mode of the mixing pump,the operational stability of the mixing pump in the quasi-closed circulation system of in-situ uranium leaching has been effectively improved.
