Abstract: In order to grasp the research progress of mine digitization in China and objectively reflect the research hotspots and trends in this field，1 095 literatures on mine digitization collected from China Na⁃ tional Knowledge Network (CNKI) from 1999 to 2022 were selected as research samples，and the knowledge map was constructed using CiteSpace software. The results show that mining digitization research has experi⁃ enced three stages: germination period，flourishing period and steady development period. It is known from the distribution of literature journals that "Metal Mine" and "Modern Mining" are the main journals in this field. The literature in the field comes from universities，enterprises and scientific research institutions， among which Professor Wu Lixin and Professor Wang Liguan in universities are in the forefront in the num⁃ ber of papers，and have made outstanding contributions to this field. Keyword analysis shows that in the past 20 years，scholars in this field mainly focus on data mining work，modeling and visualization technology re⁃ search and system framework characteristics，and future research will be more around the "intelligent (intel⁃ ligent) mine" and "green mine" and other topics. The results of literature analysis based on CiteSpace can provide reference for the research of mine digitization in the future.
