After the sealing of the fire area in 8101 extra-large fully mechanized face in Tongxin Mine, the spontaneous combustion was put out by driving a service roadway, drilling holes from the roadway into the fire area and injecting fly ash slurry and nitrogen gas from the holes into the fire area. After the reopening of the sealing area, the re-burning of the fire area was effectively controlled by taking some measures including changing the ventilation mode, reducing air quantity, blocking air leakage, nitrogen injection by buried pipes and gas control. This paper analyzed the cause and location of spontaneous combustion in the fully mechanized caving face, and summarized the fire extinguishing methods and effect of the sealed fire area in the fully mechanized caving face and the re-burning prevention method after the fire area reopening.
