[0002] During the coal mining process, there is a large amount of gas in the coal seam. In order to avoid gas explosion during the mining process, it is generally necessary to drain the gas in the coal seam. The specific process of coal mine gas drainage is as follows: First, drill holes into the coal seam and the gas accumulation area, then use a grouting hole sealing device to seal the drill holes, and then use a drainage device to extract the gas in the coal seam and the gob area and collect it for centralized utilization.
[0003] However, the existing gas control hole sealing devices have the following disadvantages:
[0004] (1) The existing gas control hole sealing devices have a weak sealing function. When in use, since it is necessary to grout into the drill hole, the slurry inside the drill hole is likely to flow out from the drill hole outlet during the slurry injection process, which easily causes slurry waste and increases the hole sealing cost.
[0005] (2) The existing gas control hole sealing devices have a weak stirring function. When in use, since it is necessary for the operator to manually mix and stir the slurry and the sealant, during the manual stirring process, it is easy to cause uneven mixing of the slurry and increase the workload of the operator.
