Coal fires cause waste of coal resources, air pollution, and threaten the safe production of coal mines, but concealed fire source detection is difficult, and a single detection method has limitations, which makes it difficult to accurately determine the location of fire source. In order to verify the detection effect of the composite detection method on the concealed fire source, according to the isotope radon detection method and magnetic detection principle, the proton magnetometer and radon meter were used to detect the hidden fire source detection area of Hengyi Coal Mine. According to the verification of subsequent anomalous area drilling, the results show that when detecting hidden fire sources, a variety of fire source detection methods can improve the accuracy and efficiency of fire source detection. The exploration and research in Hengyi Coal Mine has laid a solid foundation for the subsequent work of extinguishing coal fires, which is conducive to the safe production of coal mines.
