Abstract: The application of liquid CO₂ in underground fire fighting was discussed. Based on the analysis and over-view of the
liquid CO₂ fire -fighting technology in underground mines, this paper analyzed and explored specific application of related
technologies in underground coal mine production in combination with engineering practice, and summarized the application
effect. The results show that the technology can effectively control the fire in the goaf and is of great significance for improving the
safety of mine operations.
Key words: mine; goaf fire; liquid CO₂; fire fighting
