Abstract

The invention discloses a dedusting agent composition and a using method thereof. The dedusting agent composition is prepared by fully mixing the following components in percentage by weight: 0.04 to 0.06 percent of sodium diisooctylester sulfosuccinate, 0.04 to 0.06 percent of empgen BB, 99.547 percent to 99.91 percent of water and 0.111 to 0.333 percent of calcium chloride, wherein the mixture of the components is pressed into a spraying dust-settling system on a coal mine working surface for spraying. In the method, the sodium diisooctylester sulfosuccinate, the empgen BB, the water and the calcium chloride are fully mixed together; and the sodium diisooctylester sulfosuccinate and the empgen BB are substances with surface activity, the molecules of the sodium diisooctylester sulfosuccinate and the empgen BB consist of hydrophilic groups and hydrophobic groups, the hydrophobic groups generally consist of long organic carbon chains, and the molecules are similar to the characteristics of surface molecule of coal dust and can generate absorption easier than water molecules, so the dust catching efficiency of the water is improved, the dedusting efficiency of the dedusting agent is over 90 percent, and the water consumption for dedusting is saved.

Description

technical field [0001] The invention relates to a dust-reducing agent for removing coal dust in coal mines and a using method thereof, in particular to a dust-reducing agent composition and a using method thereof. Background technique [0002] At present, the dust concentration of fully mechanized mining face can reach 2500 mg / m without dust prevention measures in coal mining face in my country. 3 -3000mg / m 3 , while the dust situation of fully mechanized caving work is more serious than that of general fully mechanized mining face. When the coal shearer is cutting coal, moving frame and coal setting in parallel, the instantaneous original total dust concentration of some coal mines is even as high as 8000mg / m 3 -10000mg / m 3 . Even if ventilation and other measures are taken, the condition of most working faces is still quite bad, and the dust concentration in the downwind direction of the shearer can reach a maximum of 10000mg / m 3 The above has seriously exceeded the na...
