摘　　要：系统介绍美国地浸铀矿山钻孔结构和承压能力试验、过滤器形式和使用、注浆方式和设备、套管性能和连接、井场浸出结束点和溶浸范围控制等技术和工艺的特点。美国地浸铀矿山采用氧气和碱法浸出工艺,所开发的钻孔施工和成井工艺以及井场运行操作针对性强,技术先进。所介绍的技术和工艺大都未在国内应用,对我国地浸采铀技术的研究和开发有一定借鉴意义。With site investigation and document reviewing on in-situ leaching of uranium mines in US, the techniques and technologies of well configuration and completion test, type and application of filter, way and equipment of cementing, special feature and jointing of easing, endpoint of well field leaching and control of leaching area have been well known and deep understood. It is the oxygen and alkaline leaching procedure that are used in US in-situ leaching of uranium mines for which the drilling and well completion as well as the behaviour of well field operation were developed, compared with insitu leaching of uranium mines in China, most of the technologies introduced above are not applied and will be referenced.
