摘　　要：介绍离子型稀土原地浸析开采时顶水工艺的重要性 ,分析了不适当顶水工艺造成采矿技术经济指标低下的原因 ,重点剖析了顶水大循环技术各实施阶段的做法和作用 ,实践证明该项技术已获得良好的技术经济指标 。This article introduces the importance of the push water circulation technique during in situ leach mining of ion absorbed rare earths and analyses the reasons why ansuitable push water circulation technique can lead to poor technical and economic results of mining of the iron absorbed rare earths. Emphasis is laid on analyzing the ways and effects of practising the grent circulation technique of push water at all stages. The practice shows that it is an effective and advanced way.
