摘要：
The rank structure of the available coking coal from distributed and unallocated underground sources shows that it remains unbalanced: the coke group (K, KO, and OS) and the lean additive (KS) are underrepresented. Only a third of the proven reserves of coking coal permit the production of optimal coking batch. Analysis of the rank structure of the coking coal produced for domestic use shows that the extraction of the coking base (K and KO) is greater than is necessary for the production of optimal batch, leading to premature exhaustion of these reserves.
