In-situ leaching uranium technology is an important means of sandstone type uranium mining in China. In-situ leaching drilling is the only channel connecting the ground to the underground ore layer, which plays an important role in uranium mining. The construction efficiency of in-situ leaching drilling affects the construction and development of the entire uranium mine. Taking a certain uranium mine as the research object, the efficiency and existing problems of in-situ leaching drilling construction from 2019 to 2020 were statistically analyzed. The results show that compared with core drilling machines, water well drilling machines have significant advantages in construction. The configuration of mud pumps, drilling depth, logistics management, and support all have an impact on the efficiency of drilling construction. Improvement suggestions have been proposed for the factors affecting construction efficiency, in order to achieve the goal of reducing costs and increasing efficiency.

地浸采铀技术是中国砂岩型铀矿开采所使用的重要技术。地浸工艺钻孔是地面连通地下矿层的唯一通道,在地浸采铀中发挥着重要作用,其施工效率影响整个铀矿山的建设和发展。以某铀矿山为研究对象,统计分析了2019—2020年地浸工艺钻孔施工效率及存在的问题。结果表明,与岩芯钻机相比,水井钻机在施工中优势明显;泥浆泵配置、钻孔深度、后勤管理和保障均对钻孔施工效率有影响。对施工效率的影响因素提出了相应改进建议,以达到降本增效的目的。
