The vast majority of explored deposits of coals of the republic are concentrated in the Ulugh-Khem basin, the total projected resources of which exceed 20 bill.t. It is substantiated that coking coal of the Ulugh-Khem basin is the most competitive resource of Tyva Republic. Low ash content, excellent caking index, low sulfur and phosphorus in coking coal of ranks GG and GZh indicate their high quality, according to these characteristics GG, GZh coal ranks take precedence over Kuznetsk and Pechora coals. About 70 bill.t of coking coal are annually mined in Russia, but there is a deficit on certain coal ranks. It is primarily related to internal prices increase for coking coal in Russia.
