Abstract

The invention relates to a chemical dust suppressing agent for mines. The chemical dust suppressing agent is characterized by being prepared from the following raw materials in parts by weight: 15 to 25 parts of alkylphenol ethoxylate, 15 to 25 parts of alpha-olefin sulfonate, 15 to 25 parts of alkyl amide propyl betaine, 3 to 10 parts of tetra-polylysine, 0.5 to 1 part of water glass, 0.5 to 1 part of calcium chloride, 0.5 to 1 part of compound of calcium lactate and calcium gluconate, 2 to 8 parts of epoxy resin, 0.05 to 0.1 part of 2-methyl sodium isocitrate, 1 to 5 parts of 1,2-propanediol and 100 parts of water. The chemical dust suppressing agent has the advantages that a surfactant and a complexing product are poisonless, and can be easily dissolved into water; the obtaining is easy, the cost is low and economical, and the surface tension is lower; a produced foam film has certain viscosity and elasticity, and the secondary pollution can be avoided.

Description

technical field [0001] The invention relates to the field of mineral mining, in particular to a chemical dust suppressant for mines. Background technique [0002] Many human activities will produce fine particulate matter or dust, which accounts for a large proportion of air pollution, such as underground blasting, thermal power plants, heating plants, combustion furnaces, mining sites, quarries, cement plants, urban is the main source of dust. The pollution caused by dust can easily lead to the destruction of ecological balance, affect the physical and mental health and life safety of surrounding people, cause civil disputes, shorten the service life of operating machines, and restrict regional economic development. Therefore, the importance of dust prevention and control is becoming more and more prominent. [0003] Scholars in the world's major mineral resource-rich countries have done a lot of research work in this area, and have developed a variety of dust and smoke su...
