With the intensification of global mineral resource development, ensuring safe production has becomeone of the urgent issues that mines must address. This study analyzes the current sources of heat and the impacts ofheat hazards at high⁃temperature tunneling faces in deep underground mining of metal mines. It also summarizes andanalyzes existing cooling technologies in terms of types, working principles, and applicable conditions, with an emphasison the deficiencies and limitations of current approaches. Based on actual future needs, 5 development trends for coolingtechnologies are proposed. The study points out that mine air⁃conditioning and cooling systems will see broader applica⁃tions in the future and highlights that energy⁃efficient cooling technologies, integration of new materials, and intelligentcooling systems represent the main directions for future research in mine cooling. The findings can serve as a referencefor developing cooling technologies for high⁃temperature tunneling faces in deep underground mining of metal minesand offer valuable insights for safe mine operations.
