Abstract:
The traditional “rapid fire control” method in Shendong Company is hard to make it work with the mining of composite coal seams. Therefore, it is necessary to adopt an efficient, long-lasting, economical and convenient fire extinguishing method to solve the fire hazard in the mine of Shendong Company. Aiming at the mining status of ultra-large goaf in the near-distance coal seams of coal mine, in this paper, the grouting range, material, method, technique, process, drainage and effect inspection of grouting area are studied. In response to spontaneous combustion of mines, a comprehensive fire prevention measure based on grouting and fire extinguishing technology has been adopted, and a good result has been achieved. Combined the technology of grouting fire extinguishing technology in Bulianta Coal Mine, the application further demonstrates that the scientific and rational application of grouting and fire extinguishing technology can effectively control the spontaneous combustion of coal mine and thus ensure the safe production of the mine.
