FIELD: mining.
SUBSTANCE: coal is mixed with water and sintering additive in disperser, whereupon it is dehydrated. As coal there are used coal slimes which are enriched by the method of oil agglomeration to ash content 4.0-7.6% wt and sulphur content 0.2-0.3% wt by means of a sintering additive at rate of mixing 1000-1500 rev/min. Produced coal-oil concentrates of dimension 2-3 mm are separated on a sieve, mixed with other grades of enriched coal-oil concentrates and are subject to coking.
EFFECT: upgraded quality of source coal charge, reduced contents of ash and sulphur in source charge and increased strength of coke.
