Abstract: The analysis of the relationship between the indicators of sintering and coking properties with the thickness of the plastic layer and the petrographic composition of coals is carried out. A significant influence of the petrographic composition on the nature of the relationship between the indicators of sintering capacity in the classification of coals was established.
The set of indicators of the thickness of the plastic layer are in close quantitative dependence on the petrographic composition, gives a complete characterization of the plastic properties of coals and practically replaces the indicators of sintering and coking properties used in the classification of coals. The results obtained, which are largely determined by the petrographic composition of the coals, can be used with sufficient accuracy to calculate the caking and coking properties when assessing the quality of coals.
