摘　　要：针对内蒙古某多层砂岩型铀矿体,设计了分层注-分层抽开采、分层注-混合抽开采、混合注-分层抽开采和混合注-混合抽开采4种试验方案,对各组试验的抽注液量、浸出情况及优缺点等进行了分析,探究了单井分层注液的可行性,突破了单井分层抽注液的关键技术。结果表明,分层注-分层抽开采方案的浸出液铀质量浓度上升速度最快,浸出效果最好,施工成本较低,具有较好的推广应用前景。For a multi-layer sandstone-type uranium ore in an in-situ leaching uranium mine in Inner Mongolia,four experimental methods of layered injection and layered extraction,layered injection and mixed extraction,mixed injection and layered extraction,mixed injection and mixed extraction were designed.The amount of injected liquid,leaching situation,advantages and disadvantages of each schemes were analyzed.The feasibility of single well layered injection was explored,and the key technology of single well layered extraction was solved.The results show that the layered injection and layered extraction method has the fastest increase in uranium concentration of the leachate,the best leaching effect,and lower construction cost,which has good application and promotion prospects.
