The modern coal processing plants in Russia operate close-loop water-and-slime circuits (without slime water discharge to external hydraulic fills). Moreover, efficient mechanical dehydration eliminates thermal drying of coal fines. As a result, preparation plants produce considerable (up to 10–12% of the total preparation volume) fine-disperse waste coal (FDWC) with particles smaller than 0.5 mm, moisture content of 30–45% and as content of 25–65%. This product lacks demand on the market, is very difficult in terms of processing and, as a rule, is dumped with or without dirt by trucks to waste piles or slime sites. Storage of such waste creates regional ecological problems. For FDWC management purposes, the technology and equipment have been developed for production and effective combustion of coal–water slurry fuel with ash entrapment and disposal. It is suggested to use the produced fuel at coal-fired thermal and hydraulic power stations. Owing to increased volume of combustion, the economic and ecological benefits are achieved as a result.
