Embodiment 1

[0028] refer to figure 1 , 2 , 3, a kind of mine foam mud bag, comprise bag body 3 and the water inlet nozzle 7 that soft material is made, water inlet nozzle 7 reversely stretches in, when bag body is filled with liquid, because the pressure of the liquid in the bag body is greater than Outside atmospheric pressure, the water inlet nozzle 7 wall surfaces are pressed and fitted together to close the water inlet nozzle.

[0029] In this embodiment, the water inlet 7 is composed of inner and outer layers, the outer layer 5 is connected to the bag body at the beginning, the outer layer 5 is connected to the end of the inner layer 6, and the inner layer 6 is deep inside the bag body, and the inner layer 6 can be attached under pressure combine.

[0030] The water inlet 7 includes a water inlet 1 communicating with the bag body and a pressure chamber 4 located on the periphery of the water inlet 1. The water inlet 7 can form a sealing port 2 under the action of liquid pressure. W...

Embodiment 2

[0042] Reference attached Figure 4 , The section of the water inlet nozzle 7 is rectangular, and the others are the same as in Embodiment 1.

Abstract

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.

Description

technical field [0001] The invention relates to a water blasting mud bag and a method for blocking coal mine blastholes by using the same. Background technique [0002] The function of gun mud: 1) Ensure that the explosive reacts fully to release the maximum energy. 2) Reduce the temperature and pressure at which the explosive gas escapes from the free surface, so that more heat can be converted into mechanical energy, and the blasting effect can be improved. 3) Prevent hot solid particles from flying directly out of the borehole. 4) Delay the direct contact between explosive gas and gas and coal dust. The quality of the sealing mud not only affects the blasting effect, but more importantly, affects the blasting safety. At present, yellow mud (or clay mud) is generally used to block blastholes, which has relatively large dust, blast smoke and harmful gases. Contents of the invention [0003] One of the objectives of the present invention is to provide a water gun mud b...
