Abstract: In order to have a more comprehensive understanding of the research hotspots and development directions in the field of coal mine geological guarantee in China, comprehensively comb the research progress of coal mine geological guarantee technology in China, and analyze the characteristics of its evolution trend, based on the literature database of China National Knowledge Infrastructure（CNKI）. CiteSpace technology was used to construct the scientific knowledge map of 416 literatures on the topics of “geological guarantee” and “transparent geology” in coal mines since 1997. Through the visual analysis of the research authors, scientific research institutions, keyword clustering, keyword evolution trend and other contents, and according to the cluster clues generated by the atlas analysis, a structured perspective of the literature features is carried out, and the research hotspots and trends of coal mine geological support are explored. The results show that: in recent years, the number of publications in the field of transparent geological support shows an overall upward trend, among which geological support, intelligent mining, geological disaster and other keywords have been the hot research hotspots; the researchers and research institutions in the research field have formed a certain group size. At present, universities and related research institutes are the major research institutes. The research stage can be roughly divided into development stage, stable stage and explosive stage.
