ABSTRACT

The research is concerned with all the fossil coal metamorphism series based on their rank classification. Currently, based on the genetic characters of metamorphic coal conversions, no proved regulatory definition of the coal layer hazardous characteristics is available. For mining forecasts, the regulatory framework uses a limited number of the classificatory parameters with properties, which have not been determined for the whole multiplicity of coals metamorphic transformation. Special features of each coal rank shall be specified using their proxy parameters. It proves that they specify different aspects of the metamorphic coal conversions, as well as other classificatory parameters. For proved forecasting the coal layer hazardous characteristics, it is necessary to use some combinations of the classificatory parameters. It is testified that any alterations of coal properties due to their inner structure conversions may be characterized by maximum and minimum values of different parameters for the same coal rank. The limit for possible alteration of the K rank coals volatile mass yield has been established in lower than normal level. It is noted that coals with the same consumer performance may in some cases be characterized by different values of the classificatory parameters, and in other cases—the coals with different values of the classificatory parameters may have the same processing behavior. It is proposed, when establishing any hazardous properties of the coal layers in addition to the industrial classificatory parameters, one should use alterations of the organic part elemental composition, mineral impurities and moisture in the whole range of metamorphism series.
