Coke quality is largely determined by the available raw coals. According to foreign specialists, coal blend quality accounts for 70 percent of the influence on coke strength CSR and 80 percent for CRI [1]. Russian specialists estimate [2] that blend composition and quality fluctuations account for 73 percent of the influence on coke strength and coke-pushing conditions. In both cases, these data refer to the classical slot-type coke oven. Naturally, if coal-preparation and cokemaking facilities are operating smoothly, coal quality accounts for 99.9 percent of the influence on coke quality. Considering the prime importance of coal as the determining factor in coke quality, it would be worthwhile to examine Russia's current situation concerning metallurgical coal supplies and the prospects for development in the context of demands on coke and coal quality in the domestic and foreign markets. This will allow us to assess how Russian coals differ from those used by foreign coke producers, which in turn could suggest ways of developing our metallurgical coal production in conformance with world requirements for coke quality.
