One of the objectives of the present invention is to provide a water gun mud bag, which has a good dust removal effect, and can reduce gun
smoke and harmful gas content. In order to achieve the above object, the present invention adopts the following technical scheme: a kind of foam mud bag for mines, comprising a bag body and a water inlet
nozzle made of soft material, the water inlet
nozzle extends in reverse, when the bag body is filled with liquid, due to The pressure of the liquid in the bag is greater than the external
atmospheric pressure, and the walls of the water inlet are pressed together to seal the water inlet. Two of object of the present invention is to provide a kind of method that utilizes above-mentioned
cement gun bag to block
coal mine blast hole. In order to achieve the above object, the present invention adopts the following technical solutions: a method for sealing
coal mine blast holes, comprising the following steps: 1) drilling; 2) placing explosives at the bottom of the holes; 3) placing explosives with detonators on the same axis, The detonating
detonator is equipped with a detonating wire; 4) Place one or two of the above-mentioned mine water bubble mud bags; 5) The yellow mud is blocked, and the detonating wire extends out of the
drill hole. The beneficial effect of the invention is that the water cannon mud bag plays a certain role when the
coal mine is drilled and blasted, and can eliminate gas,
smoke and dust, is hygienic and safe, and is convenient to use.
