摘　　要：基于地浸采铀钻孔浸采效率问题,研发了新型开窗切割式钻孔;通过填砾式钻孔与开窗切割式钻孔的现场施工和溶浸效果对比,分析了两种钻孔结构的优缺点。研究表明,开窗切割式钻孔施工质量可控,钻孔运行稳定时间长,溶浸效果好,浸出液铀浓度上升快,回采率高。两种结构钻孔的对比使用,为地浸采铀矿山的开采提供了重要的理论依据与实践经验,开窗切割式钻孔有助于提高铀资源开发利用率。Based on the efficiency of uranium extraction drilling,a new type of cut-window drilling was developed.The advantages and disadvantages of two different drilling structures were analyzed by comparing the site construction and leaching effect of gravel filling drilling and cut-window drilling.The results show that the construction quality of cut-window drilling is controllable,the drilling operation stability is long,the leaching effect is good,the uranium concentration in the leachate rises quickly,and the recovery rate is high.The comparative use of the two structures provides important theoretical basis and practical application experience for the mining of uranium mine,and the cut-window drilling is helpful to improve the exploitation and utilization of uranium resources.
