Abstract: In this work, the objects of the study were CWC coals (coking weakly caking coals). The samples were characterized by technical analysis, which showed that the coals are close in ash content (Ad = 3.4-8.4%) and the yield of volatiles (Vdaf = 18.4-21.4%). Petrographic analysis determined the vitrinite reflection index (Ro, r), which showed that the studied coals, according to the genetic classification, belong to the 11-13 class, corresponding to the CWC grade coals. Based on the vitrinite reflectance index, re… Show more
