Abstract: Abstract: In order to systematically grasp the research progress in the field of non-coal dust explosion suppression, China Knowledge Network (CNKI) was used as the data source to analyze the digital characteristics of 108 documents in the field of non-coal dust explosion suppression using the bibliometric method, and the VOSviewer software was used to draw the knowledge map to explore the research evolution, hot spots and frontiers. The results show that: The number of research papers in the field of non-coal dust explosion suppression shows a trend of steady growth, and the research process can be divided into three stages; The selected 108 papers mainly focus on safety science and disaster prevention, mining engineering, organic chemical engineering and other disciplines; The research focuses mainly on combustible dust explosion, detonation suppressor, detonation suppression system, detonation characteristics and suppression mechanism, etc. It is the trend that the research in this field changes from the study of macroscopic measures to the study of microcosmic mechanism.
