Celem pracy było określenie zmian właściwości koksotwórczych węgli wynikających z ich utleniania podczas długotrwałego przechowywania. Przedmiotem badań były krajowe węgle koksowe oraz skomponowana z nich mieszanka do produkcji koksu wielkopiecowego. Badania wykazały, że dla wszystkich węgli nastąpił znaczący spadek ważnych wskaźników koksotwórczych oraz odnotowano pogorszenie się jakości koksu otrzymanego z mieszanek. Otrzymane wyniki porównano z danymi literaturowymi.

The aim of this paper was to determine the changes of coals coking properities, caused by oxidation during long-term storage. research material consisted of domestic coking coals, and blast-furnace blend composed from them. The research has shown, that a considerable decrease of important coking properties and deterioration of quality of coke produced from those coal blends took place in case of all coals. The obtained results were compared with data retrieved from literature.
