In fact, the working principle of mining hole sealer is very simple. The grouting tube of the mine hole sealer is connected with the grouting pump. The slurry quickly enters the two sacks due to the grouting pressure, which causes it to expand rapidly, so that the outer layer of the sack is fastened to the inner wall of the coal seam hole and the inner layer is fastened The outer diameter of the pumping pipe is used to seal the two ends of the sealer. When the pressure value reaches a certain value, the blasting valve starts to blast, and the slurry fills the middle of the two sacs to achieve a multi-layer pressure-type seal. After the slurry is completely solidified, gas drainage is performed through a gas drainage pipe. In this way, this is the working principle of mining hole sealer.
