Comparative analysis of domestic and foreign coal mine safety supervision modes based on knowledge map

In order to grasp the research status and hot frontier of coal mine safety supervision mode in the world in the past 40 years, this paper takes the relevant literature in the field of "coal mine safety" and "supervision" included in the core collection of Web of Science (WOS) and the core journals of CNKI as the data source; based on the methods of statistical analysis and bibliometrics, the visualization analysis software CiteSpace is used to draw the map of scientific knowledge. Through the visualization analysis of the main research institutions, countries, and authors in this field, the main research forces and the distribution of researchers in this field are described. Through the visualization analysis of key words and research clustering, the research hotspots and future development trends in this field are described. The results show that the research hotspots of coal mine safety supervision mode at home and abroad are roughly the same, and the researchers and institutions in this field still need to further carry out cross regional and cross departmental wide area cooperation.
