Analysis of influencing factors on the drilling efficiency of uranium geological drilling and suggestions for improvement

Abstract:

Uranium is an important strategic mineral resource in China. The relevant ministries and commissions of the state， China Geological Survey， China Nuclear Industry Geology Bureau， and many provinces and autonomous regions such as Sichuan， Shandong， Ningxia and Guangxi have clearly increased their investment in uranium geology in the new round of strategic action of prospecting breakthrough. In this paper， combined with the achievements of scientific research projects in production implemented by China Nuclear Industry Geology Bureau in 2021-2022， and the good process practice of some geological exploration units， the influencing factors of geological exploration and drilling production efficiency are systematically analyzed by using the calculation model of meterage per drill working-month， and suggestions on improving quality and increasing efficiency in the whole process of drilling production are put forward， including four specific suggestions， such as improving the pure drilling speed， the utilization rate of table month time， the actual drilling rate and the utilization rate of production table time，focusing on process optimization and introduction of mature tools and instruments. The suggestions and methods for improving drilling efficiency put forward in this paper have been partially verified during the implementation of scientific research projects in production in recent two years， and some achievements have been made in reducing costs， improving quality and increasing efficiency， so it is necessary to further consolidate and explore. Finally， the paper summarizes the general suggestions on production management， equipment renewal， technology citation and talent team construction to ensure the efficiency of uranium geological drilling， which provides a reference for the improvement of geological drilling technology and management.
