Abstract: In order to investigate the actual coal temperature distribution and development trend at the site, take the low metamorphic steady state coal at the 1305 working face of Dananhu No.1 mine during the equipment withdrawal period as the research object, and the infrared thermal imager is used to collect the entire working face temperature data. Origin data analysis software was used to analyze the temperature distribution of working face and its temperature rise law. The results show that after taking anti-fire measures such as the goaf surface coal full-section shotcrete plugging, the coal from roof beam to shield beam of the hydraulic support has a higher risk of spontaneous combustion, and the position with higher initial temperature is concentrated in the lower part of the working face. In general, the coals near the hydraulic support and the goaf surface has a trend of 0.5 ℃ to 1 ℃ increase every 2 days. During the equipment withdrawal period, affected by factors such as ventilation, recycling progress, and fire prevention technical measures, the coals in various regions show slowly rising trend based on the initial temperature, and no residual coal spontaneous combustion occurs in the working face.
