In accordance with the difficulties in monitoring surface temperature for spontaneous coal waste piles,infrared thermal imaging technology was used to monitor the surface temperature,so as to study the influence of detecting distance on measurement accuracy.By taking field experiments,a distance-temperature compensation model which based on the quantitative relationship between the infrared temperature and real temperature was established to compensate for infrared detection.The results showed that the infrared detection relative error was 0.609,and the maximum relative error was only 0.081,which was approximate to the true value after amended by mathematical model. Meanwhile,other influence factors for detecting surface temperature were analyzed.Methods of improving measurement accuracy and reducing error were correspondingly proposed.The study was of practical reference to detect the surface temperature for coal waste piles based upon infrared thermal imaging technology,and offered foundation for deep temperature detection and control.
