The trends of the development of power engineering and coke chemistry, the major consumers of black and brown coal, were analyzed. A substantial potential of an increase in the fraction of coal used in power engineering was shown. Broad application of the technology of blowing up dust-coal fuel in coke chemistry for obtaining cast iron, on the one hand, decreases substantially the amount of metallurgical coke consumed, on the other hand, it requires substantial improvement of its quality. Possible directions of an increase in the quality of blast-furnace coke, improvement of the raw material basis of dust coal fuel for blast furnaces and the production of special kinds of coke are considered. New directions of obtaining synthesis gas were proposed on the basis of the working coke chemical and metallurgical plants by means of mixing the coke and converter gases, as well as by means of gasification of tar-water emulsions. The promising character of the Russian method of catalytic coking having no analogues in the world was demonstrated. Implementation of this method will allow one to develop the fundamental scientific approaches to making coal mixtures for coking, and to propose efficient methods of their preparation. A promising home technology of energy-technological processing of brown coal from the Kemerovo Region was developed on the basis of semi-coking using a solid heat carrier. A method to obtain pitch substitutes for the production of elite sorts of needle-like coke was developed; it includes soft thermal dissolution of a definite kind of coal in technical oil extracted from coke chemical tar. The advantages of the technology of preparation and combustion of water-coal fuel were demonstrated: 1) relative cheapness; 2) availability of the raw material; 3) ecological safety of combustion process; 4) the approved character of the process (transportation of the suspension along pipelines at a distance of 200-600 km was mastered, and about 600 thousand t of the fuel was processed). A method to prepare energy gas for underground coal gasification having no analogues in the world was developed; it allows a substantial (by 40 %) decrease in capital investment for the construction of the set-up and almost 2-fold decrease in the time of recoupment of capital investment. The proposals are aimed at the use of the potential of the unique coal basin situated in the Kemerovo Region.
