Problems solved by technology

When using traditional water blasting mud to seal the blast hole, because the traditional water blasting mud only contains a certain amount of water, the specific gravity of the toxic gas that can be dissolved is small, and the effect of flame suppression and dust reduction is not good.
In addition, due to the low strength and density of the packaging film used in traditional water blasting mud, low strength and high elongation, the packaging film is easy to deform and seep water. After denaturation, it cannot fully contact with the blast hole wall and cannot achieve a good seal. Plugging effect and improving the effect of blasting coal falling

Abstract

The invention discloses high-efficiency chemical water-stemming which comprises an outer packaging film (1) and a liquid (2), wherein the liquid (2) is sealed in the outer packaging film (1); the liquid (2) comprises components in parts by weight as follows: 6-8 parts of a smoke eliminating agent, 6-9 parts of a flame eliminating agent, 5-7 parts of a foaming agent, 6-7 parts of a detergent, 7-9 parts of a dust depressor and 60-70 parts of water; the main component of the smoke eliminating agent is a mixture of sodium carbonate, sodium hydrogen carbonate, sodium phosphate and sodium silicate; the main component of the flame eliminating agent is a mixture of potassium sulphate, potassium nitrate, sodium chloride and potassium chloride; the main component(s) of the foaming agent are / is sodium nitrite and / or potassium nitrite; the main component of the detergent is sodium dodecyl benzene sulfonate; and the main component of the dust depressor is a mixture of water-soluble polymer, glycerol and calcium chloride. The high-efficiency chemical water-stemming has excellent effects of degrading and dissolving poisonous gases, eliminating smoke and flame, suppressing dust and blocking blasting holes; the cost is low; and the high-efficiency chemical water-stemming is widely applied to fields where the space of a roadway is small, the wind speed is low, and poisonous and hazardous gases are difficult to dilute.

Description

technical field [0001] The invention relates to the technical field of gun-dug roadway gun smoke control, in particular to a chemically efficient water gun mud. Background technique [0002] At present, mine rock roadways are still mainly constructed by drilling and blasting. Due to the unevenness of blasting technology, the proportion of blasting accidents and gas and coal dust explosion accidents caused by blasting is still high, which is one of the main factors causing major safety accidents in coal mines. Among them, the accidents caused by poor plugging of blastholes account for more than 25%. Therefore, it is an important means to solve blasting accidents to study reasonable plugging methods and use new water blasting mud to replace traditional water blasting mud. [0003] The function of water cannon mud: (1) After the explosive explodes, the water cannon mud can form a layer of water curtain under the impact of the explosive gas, which can reduce the explosion tempe...
