Abstract

The invention relates to a dust and smoke suppressor for mines. The dust and smoke suppressor is prepared from the following raw materials in parts by weight: 15-25 parts of alkylphenol ethoxylates, 15-25 parts of alpha-olefin sulfonate, 15-25 parts of alkyl amide propyl betaine, 0.5-1 part of calcium chloride, 0.5-1 part of calcium glycinate, 0.05-0.1 part of 2-methyl sodium isocitrate, 1-5 parts of sodium polyglutamate, 1-5 parts of 1,2-propylene glycol and 100 parts of water. A surface active agent used by the dust and smoke suppressor for the mines and the compound product of the surface active agent are free from toxicity, easily soluble in water and easy to obtain, so that the dust and smoke suppressor is relatively cheap and economical; the dust and smoke suppressor for the mines has lower surface tension, can produce a foam film with certain viscosity and elasticity, and can avoid secondary pollution.

Description

technical field [0001] The invention relates to the field of mineral mining, in particular to a dust and smoke suppressant for mines. Background technique [0002] Many human activities will produce fine particulate matter or smoke, 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 ...
