This article starts from the characteristics of the 1303 fully mechanized top coal caving face in the first coal mine of Dananhu, combined with relevant data and drawings of the mine and experimental working face in the first coal mine of Dananhu, and based on the characteristics of spontaneous combustion of residual coal in the goaf after mining of the fully mechanized top coal caving face, using on-site measurement methods, calculates the limit parameters such as residual coal thickness, wind speed, oxygen concentration, etc. that cause spontaneous combustion of coal under different conditions on site, And calculate the distribution pattern of the "three belts" in the 1303 fully mechanized top coal caving face of Dananhu No.1 Mine under actual conditions. And divide the "three zones" of the goaf in the 1303 fully mechanized caving face. Based on the results of the division of the "three zones", the distribution pattern of spontaneous combustion in the goaf is calculated and determined, and combined with the shortest ignition period of residual coal in the 1303 working face measured through experiments, the safe propulsion speed is calculated. Finally, a reasonable set of fire prevention and extinguishing technologies and methods were summarized, providing important guidance for the future fire prevention and control of the Dananhu No.1 Mine and surrounding mines, and providing experience and reference for the application and development of fire prevention and extinguishing measures in the future.
