摘　　要：针对离子型稀土矿山原地浸矿工艺信息化水平较低、注收液效果差、难以实现精细化开采等问题,采用传感器技术、西门子S7-300可编程序控制器(PLC)系统和上位组态管理系统,实现原地浸矿注收液过程流量、液位、pH值等关键参数在线监测与管理,实现离子型稀土矿山开采注收液优化控制,提升稀土矿山自动化水平,提高生产管理水平和生产效率,对实现稀土矿山绿色开采起到重要作用。Aiming at the problems of low information level of in-situ leaching process in ionic-type rare earth mines,poor effect of liquid collection and injection and difficult to realize fine mining. The sensing technology, Siemens S7-300programmable logic controller(PLC) system and upper configuration management system are adopted to realize the on-line monitoring and management of key parameters such as flow, liquid level and p H value in the process of injection and collection of in-situ leaching solution, realize the optimal control of injection and collection solution in the mining of ionic rare earth mines, improve the automation level of rare earth mines and the production management level and production efficiency, and play an important role in realizing the green mining of rare earth mines.
