[0002] The working principle of a coal mine fire prevention grouting device is relatively simple and effective. First, fire prevention grouting materials (such as yellow mud, fly ash, etc.) are mixed evenly in a certain proportion and stored in a liquid storage tank. Then, a high-pressure pump is started, and the slurry is transported through a pipeline to a grouting pipe. The grouting pipe conducts grouting operations at appropriate positions in the coal seam or goaf, and the slurry diffuses in the coal seam and forms a protective film to prevent oxygen from entering the coal seam, thereby preventing spontaneous combustion of coal.
[0003] Regarding the above related technologies, the defect of the existing grouting device is that during the process of injecting materials, part of the slurry adheres to the inner wall of the grouting pipe. The long-term accumulation of the slurry will cause blockage of the grouting pipe and affect the use. Therefore, the utility model provides a coal mine fire prevention grouting device.
