Abstract: In order to explore the research trends of thermodynamic disaster in coal mine, based on the perspective of information visualization, 2 845 related papers published in CNKI database from 2002 to 2021 were used as data sources, and CiteSpace was used to conduct scientific measurement analysis on the number of papers, authors, institutions and keywords. The research shows that the research on thermodynamic disaster in coal mine generally shows three stages: slow growth, steady growth and stable development. DENG Jun, WANG Deming, YU Minggao, WEN Hu are the main core authors in this field. China University of Mining and Technology, Xi’an University of Science and Technology, Liaoning Technical University, China University of Mining & Technology（Ｂｅｉｊｉｎｇ） are the main research institutions in this field. Hot keywords mainly focus on gas explosion, coal spontaneous combustion, numerical simulation, mined-out area, etc. The research emphasis in this field is mainly embodied in the research of spontaneous combustion characteristics of coal and gas explosion, in which numerical simulation is an important research method. At present, there are few studies on coal mine thermal power compound disasters and disaster monitoring and early warning. In the future, the research on these two aspects can be strengthened.
