FIELD: chemistry.
SUBSTANCE: invention relates to labour protection and environmental protection in mining industry and can be used for dust suppression and reduction of dust transfer during mining operations. Disclosed is a preventive composition for preventing dust release and dust propagation. This composition contains the following components in the specified ratios, wt.%: polyvinyl alcohol 2-4, biofuel production wastes (in terms of pure glycerine) 0.05-0.15, sulphonol 0.5-1.5, ethylene glycol 10-20, water – the rest.
EFFECT: reduction of pour point of the dust suppression composition to minus 10 °C, which will allow using the agent at subzero temperatures.
