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.
