Review of Theory and Technology Research on Prediction of Coal Spontaneous Combustion

On the basis of collecting and collation of the domestic and foreign literature on the theory and technology of coal spontaneous combustion prediction in recent years, the research of prediction of coal spontaneous combustion was summarized and analyzed from three aspects, including prediction theory of coal spontaneous combustion, monitoring technology of coal spontaneous combustion and detecting technology of concealed fire source. The advantages and disadvantages of existing coal spontaneous combustion monitoring technology were pointed out and the applicable conditions were defined; the characteristics and technical approaches of commonly used concealed fire detection technology were analyzed, and their advantages and disadvantages were compared and analyzed, the future coal spontaneous combustion prediction theory and technology development trend were prospected.
