摘　　要：随着地浸技术的发展,一些新工艺很难简单地用传统的酸、碱分类方法进行界定,出现工艺归类与地浸实际工作状态不一致的现象,也造成了技术交流的不便。在综述目前主要地浸工艺及其铀迁移原理的基础上,对地浸采铀工艺分类方法进行了探讨,提出了分别以地浸工作液pH和浸出铀的迁移形式为依据的分类方法。With development of technology of in-situ leaching uranium mining,it is difficult to define some new techniques by traditional classification methods by which the in-situ leaching techniques are grouped into acid leaching and alkaline leaching.Confusion and inconvenience occur during technological and academic exchanges due to inconsistencies between classification and actual in-situ leaching conditions.Based on the review of main techniques of in-situ leaching and uranium migration theory,the classification methods of in-situ leaching uranium mining technique were discussed,and improved classification methods were proposed based on pH value of leaching solution and migration form of dissolved uranium respectively.
