In view of the limitations of the existing coal fire detection technology, the current research status of coal fire detection technology is summarized, and it is pointed out that the current mainstream measurement methods of hidden high temperature points in loose coal bodies in mining areas can be divided into two categories: contact temperature measurement and non-contact temperature measurement; the current research status of acoustic temperature measurement technology is reviewed, the temperature-sensitive characteristics of acoustic waves and the propagation characteristics of acoustic waves are analyzed, the current research status of combustion sound is summarized, and combustion sound generation mechanism, combustion sound frequency under different conditions and the fire detection technology based on combustion sound identification are analyzed. The concept of a new coal temperature sensing technology is put forward by studying the propagation characteristics of applied sound waves with different frequencies in heating loose coal, grasping the influence of different experimental conditions on the propagation law of "dual source" composite sound waves of external acoustic wave and combustion sound., authors=GUO Jun^1,2,3, ZAN Ruoyi^1,2*, WEN Hu^1,2,3, WANG Kaixuan^1,2, JIN Yongfei^1,2,3, authorsList=GUO Jun, ZAN Ruoyi, WEN Hu, WANG Kaixuan, JIN Yongfei, authorCompany=1.
