Abstract
The invention has one aim to provide a water stemming bag which has favorable dust removal effect and can reduce blast fume and decrease harmful gas content. In order to realize the aim, the water stemming bag for coal mine comprises a bag body and a water nozzle, wherein the water nozzle is made of flexible materials; the water nozzle reversely enters; and when the bag body is filled with liquid, the wall surface of the water nozzle is pressed to be attached together to seal the water nozzle because the pressure of the liquid in the bag body is larger than external atmospheric pressure. The invention has the second aim to provide a method for sealing a coal mine blast hole by utilizing the water stemming bag. In order to realize the aim, the method for sealing the coal mine blast hole comprises the following steps of: (1) drilling; (2) charging explosive to the bottom-most part of the hole; (3) charging explosive with a detonating primer on the same axis and installing a detonating lead on the detonating primer; (4) placing one or two water stemming bags for coal mine; and (5) sealing with yellow mud and extending the detonating primer out of a drilling hole. The invention has the advantage that the water stemming bag has certain effect when the coal mine is punched and blasted, can extinguish gas, smoke and dust, is sanitary and safe and is convenient for use.
Description
Technical field
The present invention relates to a kind of water stemming material bag and utilize the method for its shutoff colliery borehole.
Background technology
The effect of stemming: 1) guarantee that explosive fully reacts, make it to emit ceiling capacity.2) temperature and pressure on the reduction detonation gas effusion scope of freedom makes more heat change mechanical energy into, improves demolition effect.3) stop red-hot solid particle from borehole, directly to fly out.4) delaying detonation gas directly contacts with gas, coal dust.The quality of sealing clay quality not only influences demolition effect, the more important thing is to have influence on shotfiring safety.General at present yellow mud (or clay mud) the shutoff borehole that uses has bigger dust and blasting fume and pernicious gas etc.
Summary of the invention
One of the object of the invention provides a kind of water stemming material bag, has good dust removing effects, and can reduce blasting fume, reduces pernicious gas content.
To achieve these goals, the present invention is by the following technical solutions:
A kind of mining bubble mud bag comprises the water inlet tap that bag and soft material are made, and water inlet tap oppositely stretches into, when bag is filled with liquid since in the bag pressure of liquid greater than external atmosphere pressure, the water inlet tap wall pressurized sealing water inlet tap that fits together.
In the embodiment of the invention, water inlet tap two-layerly is made of inside and outside, and outer top connects bag, the outer terminal end that connects internal layer, and internal layer top gos deep into bag inside, and internal layer is fitted by pressure energy.
In the embodiment of the invention, water inlet tap comprises the inlet opening that communicates with bag and is positioned at the balancing gate pit of inlet opening periphery that water inlet tap can form seal under the fluid pressure effect.
In the embodiment of the invention, the water inlet tap cross section is inferior font.
In the embodiment of the invention, water inlet tap and bag are integral structure.
In the embodiment of the invention, water inlet tap and bag adopt the mold pressing of polyethylene film by heat-conglutinating machine to make type.
Two of the object of the invention provides a kind of method of utilizing above-mentioned cement big gun bag shutoff colliery borehole.
To achieve these goals, the present invention is by the following technical solutions:
The method of a kind of shutoff colliery borehole may further comprise the steps:
1) boring;
2) explosive is placed in the Kongzui bottom;
3) place the explosive of being with detonating primer on the same axis, the ignition lead is housed on the detonating primer;
4) place one or 2 above-mentioned mining bubble mud bags;
5) yellow mud shutoff is ignited lead and is stretched out outside the boring.
Beneficial effect of the present invention:
The water stemming material bag punches in the colliery and plays a role the gas that can go out, the cigarette that goes out, the dust that goes out, safe and sanitary, easy to use when blowing out.
