Abstract: In order to study the heating characteristics and transfer law of high temperature heat source in goaf, the infrared measurement test of heat source temperature in goaf was designed, and the relationship between the heat transfer law of high temperature heat source and the temperature change in the infrared measurement test was analyzed. The results show that the temperature of both the high temperature heat source and the measuring point increase exponentially with time, and the temperature of the measuring point decays in the form of a quadratic function with the increment of the distance between the measuring point and the heat source; under the condition of constant temperature heat source, with the increase of heat source temperature, the temperature of the measuring point increases in a quadratic function law, but with the increase of heat loss in the process of heat transfer, the increment of temperature of the measuring point decreases; by comparing the temperature changes of measuring points under dynamic and steady heat source conditions, the temperature correction formula of the infrared measurement test of the heat source is obtained through the analysis of experimental error, which can be used for real-time monitoring and correction of the actual temperature of high temperature heat source in goaf.
