Abstract

The invention provides a wet-type water-retaining property dustfall agent. The wet-type water-retaining property dustfall agent comprises, by weight, 0.2%-0.15% of starch grafting acrylate, 0.5%-2% of lauramidopropyl betaine, 0.01%-0.1% of cetyl trimethyl ammonium bromide, 0.2%-0.6% of sodium dodecyl sulfate, 0.3%-0.8% of sodium dodecyl benzene sulfonate, 0.1%-0.3% of sodium dodecyl sulfate, 0.4%-1.3% of sodium N-oleoyl-N-methyltaurinate, 0.02%-0.3% of dodecyl dimethyl betaine, 0.2%-0.6% of cocoanut fatty acid diethanolamide, 0.1%-1% of sooctyl alcohol sodium sulfate and the balance water. The wet-type water-retaining property dustfall agent is compressed by a hydraulic device and then forms mist spray to be sprayed to dust production points by nozzles, foam collides with dust particles in the air after being sprayed out, hence, high-concentration dust can be caught and settled, the surface tension of the water can be effectively lowered, the water spray can better wrap the dust, the high wetting water-retaining property is achieved, the dust concentration on an excavation working face can be effectively lowered, and the dust on the working face can be restrained for a long time.

Description

technical field [0001] The invention relates to a coal mine underground dust removal additive, in particular to a wet water-retaining dust reduction agent. Background technique [0002] With the improvement of mechanized production level in the mine production process, the dust production of underground mining face also increases rapidly. According to actual measurements, without any dust prevention measures, the dust concentration of fully mechanized excavation face can reach 2000mg / m 3 -3000mg / m 3 , the dust concentration in the fully mechanized mining face can reach 2500mg / m 3 -3000mg / m 3 , and the fully mechanized caving face can produce a large amount of dust due to the process of moving frames and coal discharge, and the instantaneous original total dust concentration of some coal mines is even as high as 8000mg / m 3 -10000mg / m 3 . The high concentration of dust seriously threatens the safe production of mines and the health of workers. [0003] In order to reduc...
