One of the most pressing issues is the effective use of coal combustion in the form of water-coal fuel, which has a number of advantages over layer or pulverized combustion. Coal-water fuel has a number of economic, operational and environmental advantages. The article considers the electric pulse method as a source of obtaining a fine product of coal-water fuel. The proposed method for grinding coal is based on the use of the energy of a pulsed shock wave resulting from a spark electric discharge in a liquid. The parameters of the electric pulse discharge for obtaining the required granulometric composition of the components of coal-water fuel are determined.
