“…For non-volatile residue with high strength characteristics of the original sample 344 should have the following parameters: 25 ≤ V daf ≤ 33%; in ≥ 16 mm; 1.0 ≤ R o ≤ 1.1. These include scarce coking coals grade K, but these requirements can meet and mix different brands [21]. This, in our opinion, can be attributed to the experimental data.…”

-The relevance of the work is justified by the need for a comprehensive assessment of the quality of coal concentrate used to produce coal blends in the coking process, and resources of coking chemical products derived from them. This information is necessary for making optimal coal blends for coking and for planning of coking plants operation. The purpose of work is to study the impact of the qualitative characteristics of the Kuznetsk Basin coal concentrates on the yield and composition of coking chemical products for the purpose of making coal blends for coking on their basis. In the course of studies, the following indicators have been identified: the technical analysis, caking, petrographic analysis, the yield of chemical coking products from coal concentrates and strength of the resulting coke residue. The main results of the study are the data on the main indicators of the quality of the investigated coals of the Kuznetsk basin and the coking yield as well as the relationships between these parameters. The results will later be used in the preparation of optimal coal blends for coking in the real production conditions of OAO "Koks".

“…This system consists of organic macromolecules passing into the liquid state, solid organic or inorganic inclusions in the liquid phase, and the gases released during heating. Increasing the thickness of the plastic layer does not always mean an increase in the sintering ability and, especially, for the coking coal [8]. Fig.…”

“…Based on the analysis of the published data [8], we concluded that in order to determine the coal coking capacity one can use the method of evaluating the strength of nonvolatile residue received after determination of the rheological properties of coal in accordance with GOST 1186-87 "Coal bituminous. Method for determination of plastometric indicators" [9].…”

“…The mechanical properties of non-volatile residue were investigated in accordance with the procedure described in [8] with the changes that take into account the nature of the method of its preparation. According to this technique, the resulting non-volatile residue was dissipated by size classes in the round sieves with 10 mm and 1mm diameters.…”

In modern conditions, one of the most acute problems for the coking industry include deterioration of raw material base for coking and coking coal deficit. The negative impact of the deterioration of the raw material condition on the yield and quality of coking products can be compensated by the increase in the level of coal blending quality management, which is primarily based on the chemical and technological properties of coal. Therefore, for the analysis of the above parameters, it is necessary to make a full use of the potential of all available coal properties valuation techniques. In the course of this work, the quality indicators of coal concentrates of the Kuznetsk Basin were defined and the strength properties of non-volatile residue obtained in determining the yield of chemical products of coking were studied. Based on the analysis of the obtained results, the experimental dependences of the reviewed parameters were built.
