摘要：
The type to which a coal belongs by its genetic state of reduction is connected with the reactivity of its organic matter in relation to oxidizing and reducing agents. The essence of the method consits in the electrochemical treatment of coal with specification the scales of the oxidation reactions in the anode space and of the reduction reactions in the cathode space of the electrochemical cell. The degree of reduction is expressed by a relative dimensionless magnitude - the reduction coefficient K//r. It is concluded from experimental data that in combination with the indices of the degree of coalification, the determination of the coefficient of reduction opens up possibilities for a more stringent separation of coals into genetic groups connected with some particular combination of their technological properties.
