| 摘 要： | 为了解决缓倾斜铀矿床原地爆破浸出开采中的爆破筑堆和均匀性浸出问题, 采用上向扇形深孔分段微差挤压爆破落矿筑堆技术、分段水平钻孔布液和泡浸浸出工艺以及巷道集液方法, 在某矿床进行了原地爆破浸出采铀工业性试验。试验研究取得了初步成功。对缓倾斜低品位铀矿床的开发利用有一定的借鉴作用。

| Abstract: | In order to obtain a desirable muck-pile formation by stope blasting for in-situ leaching and more uniform leaching rate of uranium from flat-dipping ore bodies,some commercial tests were carried out on the in-situ leaching of uranium after stope blasting in a mine by using the following methods and technologies,including muck-pile formation by upward deep-hole sector millisecond compression blasting,pumping leachate solution into ore bodies via sublevel horizontal boreholes,infusion leaching and leachate collection in headings.The successful preliminary study results from those tests can be taken as reference for further exploitation and utilization of flat-dipping and low-grade uranium ore bodies. |
