Abstract: Anchor support technology is widely used in the control of surrounding rock in geotechnical engineering, especially in the maintenance of deformation in underground coal mining tunnels. Summarizing the existing research results of anchor support technology and further exploring the development of anchor support technology, this paper uses CiteSpace software to conduct quantitative analysis of relevant literature in the past 20 years, classifying and statistically analyzing research hotspots from the aspects of publication volume, authors, institutions, keyword clustering, time zone, etc. Research shows that in the past 20 years, China has temporarily occupied a dominant position in the field of anchor support technology research in the world. In the early 21st century, the research on anchor support in China mainly focused on on-site engineering applications, and gradually paid attention to the study of the refined internal mechanism of anchor bolt anchoring after 2010; However, the number of English publications during the same period is relatively low. The core authors appear in small teams, and there is relatively little communication between domestic and foreign scholars. The research on anchor support technology is mainly conducted by universities, and there has not been extensive cooperation among institutions in various regions. From the evolution of keywords, it can be seen that the research on positive anchor support technology can better adapt to the harsh geological environment control exploration of deep coal mining, and the exploration of new materials and processes for anchoring is constantly advancing. On this basis, the practical problems encountered in anchor support in deep formations are further discussed in detail, and a summary and outlook are proposed for high-performance anchoring materials, reasonable anchoring lengths, and ground pressure control modes. The research results provide certain technical references for the application of anchors in geotechnical engineering, especially in deep coal mining engineering support.
