Petrographic and chemical-technological characteristics coal seamsof the lower carbon,formation C12 of the kalmiusblock

Purpose. To establish the petrographic and chemical-technological features of coal seams formation C12 Kalmius block. Method. General scientific applied research methods were used to fulfill tasks. With help methods, macroscopic microscopic characteristics composition studied in detail, degree its recovery metamorphism was determined. chemical technological a comprehensive description quality is provided. The use modern analysis interpretation made it possible provide generalized characteristic seams, reveal peculiarities their quality. Findings. For first time, regional ("provincial") for Lower Donbass revealed. Their typical determined on block square. It established that differs from C13 both terms gross maceral composition. In addition, they are characterized by different degrees recovery. proved stratigraphic section, layers lower world upper world, number groups inertinite liptinite increases, vitrinite decrease. Lateral regularities changes that, compared C13, higher values sulfur content, heat combustion, thickness plastic layer, Rog index C12. elemental carbon hydrogen content significantly amount oxygen. Changes Carboniferous originality. section Southern Donbas, which indicate conditions peatlands, established. Practical implementation. region's have been clarified, lateral indicators determined, grade according new current standard Ukraine has established, value calculated.
