The paper presents methods of evaluating the effectiveness of reactants to reduce the freezing of coal products. When choosing such a reactants, an important indicator is the dynamics of changes in their properties during freezing. It is shown that the reactants property not turning into solid (crystalline) state at temperatures -40 and -60 оС are more efficient in reducing the freezing of coals of different rank. It is noted that treatment of coals with such reactants leads to an increase in their total moisture content after freezing-thawing cycle as compared to the untreated coals.
