Abstract: With the continuous exploitation of coal resources, the economic losses and casualties caused by coal spontaneous combustion have become increasingly prominent. It is of great significance to study the mechanism of coal spontaneous combustion, coping strategies and utilization of coal fire resources to promote the green prevention and control of coal spontaneous combustion. This paper summarizes and combs the research status of coal spontaneous combustion, mainly reviews the mechanism and prevention technology of coal spontaneous combustion, the thermal dynamic evolution of coal fire disaster and the extraction and utilization of coal fire thermal energy. The purpose is to provide reference for the research and practice in the field of coal spontaneous combustion, and to promote the effective control of coal fire disasters and the rational use of resources.
