An efficient trend in the intensification of the byproduct coke and blast-furnace industries seems to be the development of an algorithm for calculations of the strength characteristics of coke, which is completely based on the information about the properties of the coals used. The properties of the coke produced may be indirectly characterized by the composition of the coal blend, but this approach does not disclose the essence of physico-chemical processes that take place during coking and is semiempirical in character [l] According to Finkelshtein [2] and Filonenko et al. [3], the coking power of coal blends is the result of the manifestation of three properties: geological maturity (metamorphism), caking capacity (plasticizing ability) and petrographic heterogeneity of coal. Apart from these predominant factors, the quality of coke is also influenced by the granulometric composition (particle-size distribution) and moisture content of the coal blend, the regime of its thermal treatment and the geometric characteristics of the coking chamber [4, 5].
