Using the method of regression analysis of statistical data on the prices of the world market of power-generating coals, it has been shown that the cost of coal fuel increases with increasing calorific value of coals and decreases with increasing ash content and total sulfur.The application of regression equations to the data on the quality indices of power-generating hard coals of the Kuzbass basin points to their sufficiently high potential competitiveness. This is primarily characteristic of ROM coals produced by open-pit mining in the basin and of many Kuznetsk coals extracted by surface and underground mining after beneficiation with respect to ash content up to 10-15 percent.Using Kuzbass coals as examples, it has been shown that the contemporary market price can be forecast for coals to be used for electricity generation and metallurgy on the basis of the internal wholesale prices and the market price for coking coals can be predicted from the coefficients of their relative technological value.
