Abstract

The invention discloses a mining dust removal foam generating agent. The mining dust removal foam generating agent comprises, by weight, 0.1% to 1% of lauroamide propyl betaine, 0.2% to 0.9% of 1-hexadecylsulfonic acid sodium salt, 0.005% to 0.08% of sodium alcohol ether sulphate, 0.2% to 0.6% of alpha-olefin sulfonate, 0.2% to 0.4% of trimethyl-1-propanaminium iodide, 0.01% to 0.03% of modified polyethoxylated silicone, 0.1% to 0.2% of poly aspartic acid, 0.006% to 0.3% of amphiprotic surfactant BS-12, 0.005% to 0.2% of hydroxyethyl cellulose, 0.4% to 0.6% of calcium chloride and the balance water. The mining dust removal foam generating agent can be kept in an even, fine and smooth state for a long time and foam dust suppression efficiency is guaranteed; the mining dust removal foam generating agent has good biological degradability and is high in environment friendliness coefficient and safety coefficient.

Description

technical field [0001] The invention relates to an underground coal mine dust removal foam foaming agent, in particular to a mine dust removal foam generating agent. Background technique [0002] In recent years, with the rapid development of coal mining technology, comprehensive mechanized mining technology has been widely used in coal mines across the country. On the one hand, the improvement of mechanization can increase the output of the mine and realize the efficient operation of the mine. On the other hand, the dust production of the underground mining face will also increase 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,...
