FIELD: coal processing industry, namely, technology for preparing water-coal suspension from coal with given rheological characteristics.
SUBSTANCE: in accordance to invention, decrease of dynamic viscosity of water-coal suspension, manufactured from coal with size ranging from 63 to 250 micrometers, is achieved due to injection of potassium humate in amount of 0,70-0,80% during suspension preparation.
EFFECT: optimal concentrations of admixtures allow maximally decreased viscosity of water-coal suspension.
