FIELD: mining.

SUBSTANCE: invention relates to the mining, in particular coal mining, industry and can be used to improve the efficiency of dust suppression and reduce air dust in coal mines, as well as in open pits, coal storages and coal preparation plants, where hydro-dedusting agents are used. The composition of the mine wetting agent contains 50-55 wt.% decylglucoside, 10-15 wt.% cocoglucoside, 5-10 wt.% cocamidopropyl betaine and water - the rest.

EFFECT: increasing the efficiency of wetting coal dust by reducing the surface tension at the phase boundary, increasing the rate of wetting of dust particles and their precipitation from the aerosol.
