Summary:Modification of the properties of clinkering and poorly clinkering coal is of interest to expand the composition of coking batch. The ash content, sulfur content, and yield of volatiles are studied after profound enrichment of coal samples. The change in properties on profound enrichment depends on the metamorphic development of the coal. Petrographic data confirm that the effect of profound enrichment depends on the initial metamorphic development of the coal. Calculations show that deep enrichment of the coal results in slight changes in the total content of clinkering components. The change is greater for coal of earlier metamorphic stages.
