Abstract: To address the lack of systematic analysis of the research status in the field of mine thermal environment, this study conducted bibliometric analysis and knowledge graph visualization research using CiteSpace software based on the China National Knowledge Infrastructure (CNKI) database, with a focus on the domestic development context and cutting-edge trends of this field. The results show that: domestic research on mine thermal environment has experienced three evolutionary phases, the slow germination period from 1994 to 2008, the rapid growth period from 2009 to 2015 (the peak of development), and the steady maturity period from 2016 to 2024; Journal of China Coal Society (4.6% of publications), Coal Science and Technology (6.5% of publications), and Safety in Coal Mines (27.4% of publications) are the core representative journals in this field; academic collaboration is mainly conducted within teams, the top three researchers in terms of publication volume are XIN Song (17 papers), QIN Yueping (12 papers), and JI Jianhu (11 papers), and the highly cited papers are mainly concentrated in five major research teams, namely the HE Manchao’s team, JI Jianhu’s team, QIN Yueping’s team, CHEN Liu’s team, and XIN Song’s team; China University of Mining and Technology (25.7% of publications), China University of Mining and Technology (Beijing) (14.2% of publications), and Shandong University of Science and Technology (13% of publications) constitute the main research forces in this field; the keyword clustering module value Q is 0.822 2 and the average silhouette value S is 0.948 1, indicating high credibility and good discrimination of the clustering results, and a total of 12 clusters have been formed with the core theme of “thermal hazard mechanism-cooling technology-numerical simulation”, and high-frequency keywords include “numerical simulation” and “temperature field”, and the current research hotspots focus on four directions, namely “numerical simulation”, “thermal hazard control”, “ventilation cooling”, and “temperature field”; research frontiers and hotspots are concentrated in the technical and application fields such as numerical simulation and ventilation cooling. Through visualized knowledge graph analysis, this study reveals the development trends and cutting-edge hotspots in the field of mine thermal environment, providing support for subsequent in-depth research in this field.
