Abstract

The invention discloses a permeability-increasing and coagulation-accelerating wetting agent for wet-type dust control. The permeability-increasing and coagulation-accelerating wetting agent comprises 0.5%-2% of cocamidopropyl betaine, 0.15%-0.8% of butylnaphthalenesulfonic acid sodium salt, 0.2%-1% of trimethyl-1-propanaminium iodide, 0.2%-1% of sucrose fatty acid ester, 1%-3% of corn starch grafting sodium acrylate, 0.5%-1.5% of isooctanol phosphate, 0.06%-0.35% of sodium alcohol ether sulphate, 0.5%-1.3% of sodium diethylhexyl sulfosuccinate, 0.2%-1.2% of polyacrylamide, 0.1%-0.8% of chitin derivative-carboxymethyl chitosan, 0.1%-0.2% of polyaspartic acid, 0.3%-0.6% of calcium chloride and the balance water. The ermeability-increasing and coagulation-accelerating wetting agent for wet-type dust control has the advantages that wetting ability of water for coal is enhanced and water molecules can wrap coal dust particles quickly, so that coagulation and falling of the coal dust particles are facilitated.

Description

technical field

[0001] The invention relates to a wet dust control wetting agent for a coal mining face in a coal mine, in particular to a wetting agent for wet dust control of a seepage-promoting and coagulation-increasing type. Background technique

[0002] In the process of efficient mechanized production in coal mines, the amount of dust produced in underground working faces continues to increase. According to the measurement, when the coal shearer cuts coal, the dust concentration of the working flour can reach 1000-3000mg / m 3 In some coal mines, the instantaneous original total dust concentration is even as high as 4000-6000mg / m 3 , Coal cutting by coal shearers has become the main source of dust production. High-concentration, high-dispersion dust diffuses the entire working face and roadway, causing the dust concentration in the working face to seriously exceed the limit. These dusts not only have the potential danger of explosion, but also reduce the service life...
