Abstract：The 2#coal seam mined on the 130203 comprehensive discharge face is a coal seam prone to sponta-neous combustion.In order to prevent the phenomenon of natural ignition in the working face during the shut-down period,after research,combined with the actual mining situation of the 130203 comprehensive discharge face,adopting a full process research method of prediction,governance,and effectiveness monitoring.The shor-test natural ignition period of the spontaneous coal seam,the coal mining method of the working face and the treatment method of the goaf area,the natural ignition prediction and forecasting were determined,the air leak-age in the goaf area,the fire prevention and extinguishing materials in the upper and lower goaf areas of the working face,the grouting and inert gas injection and other technical solutions for preventing and controlling natural ignition were determined.Practice has proved that the natural ignition of the coal seam was not detec-ted during the shutdown of the 130203 comprehensive discharge face,and the safe production of the working face was successfully realized.
