High-efficiency chemical water-stemming

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.
