In order to ensure the safe production of the re-mining face,we focus on the problem of spontaneous combustion of coal seams on the re-mining face,and put forward a comprehensive fire prevention technology applicable to the remining face of the mine on the basis of analysis of the site conditions of the F1301 re-mining face in Canal Mine and the risk of the spontaneous combustion of the coal remnants.The effective means are adopted,such as wind flow field regulation,pressure equalization and leakage plugging,inerting treatment,monitoring and detection,etc.We qualitatively analyze the mechanism of fire prevention and extinguishing under the conditions of re-mining,standardize the fire prevention and extinguishing tech-nology,and quantify the fire prevention and extinguishing technical parameters.The risk of the spontaneous combustion on the driving face is effectively controlled to ensure the smooth progress of F1 301 re-mining face.
