【Abstract】 Fully mechanized caving mining method is used in Xingtai mining area to mine the high sulfur content lower-coal seams,and this will cause coal liable to spontaneous ignition.To settle this issue,the author analyzed the characters of coal seams spontaneous ignition and index gas,and a comprehensive technology system for fire prevention and fighting is established through setting up a monitoring and forecasting system,using three-phase foam extinguishing material,making gunniting to roadway by using compounding material to seal oxygen,and using equal-pressure fire prevention technology.A sound result has been achieved based on above.更多还原
