Calculating the relative value of coal in Russian coking-coal markets

In order to improve the pricing of Russian coking coal, a method is proposed for calculating the relative technological value of purchased coking-coal batches. The basic idea is to compare the parameters of optimal coking batch and coking batch that includes the purchased coking-coal concentrate and other coals available to a particular buyer. It is shown that the relative technological value of a particular batch of coking-coal concentrate will depend on the parameters of the other coals included in the coking batch at a particular coke plant.
