The present investigation was carried out to examine the interactions between Donbas, Karaganda and L'vovsk-Volynsk coals in carbonization blends, with a view to easing the coal supply situation at the Dneprodzerzhinsk C and CW. Am improvement takes place when the vitrinite from non-caking coals is carbonized in the presence of leptinite-rich coals. L'vovsk-Volynsk coals come under this category; the organic substance includes 10% of leptinite. Karaganda and L'vovsk-Volynsk coals thus have opposite effects on carbonization behavior, and when both are included in the blend it is possible to produce a coke of the same physicomechanical characteristics and mechanical strength as coke made entirely from Donbas coals. Metallurgical coke of satisfactory quality can be produced from blends containing Donbas, Karaganda and L'vovsk-Volynsk coals simultaneously. In view of the growing shortage of Donbas coals and the availability of new reserves in the Karaganda and L'vovsk-Volynsk coalfields, the supply situation in the Ukrainian coking plants should be improved by devising blends with up to 20% each of these coals for the production of metallurgical coke. The caking base still consists of Donbas coals, but the reserves of grade Zh, K and OS coals are approaching exhaustion and the newly prospected regions contain a major proportion of grade G coals (up to 60%). L'vovsk-Volynsk coals provide an attractive source of additional supplies, and can be mined under more favorable conditions. They have hitherto been used as boiler fuel, but trials have shown that they can be blended with coals from Eastern coalfields to produce metallurgical coke of satisfactory quality at considerably lower cost.
