  • Descrição: It is shown that the inhomogeneity of coal mixtures (enrichment-plant concentrates) differing in vitrinite reflection coefficient and the content of clinkering components (i.e., in the deviation of these parameters S R and S CC ) may only be objectively estimated on the basis of refractogram and petrographic analysis of bed samples of the coal from the mines that supply the enrichment plant. A method and corresponding program for calculating S R and S CC is proposed. This program permits correct determination of the petrographic inhomogeneity of coal batch, which is important in evaluating the influence of this factor on coal quality.
