Genetic classification of coal-bearing formations

Abstract

By the end of preliminary exploration, there is usually already enough data for geological and industrial characterization of the mine field. However, the reliability and validity of conclusions will increase significantly if one uses some more general regularities of coal geology. The thickness and structure of the coal seam, petrographic composition, ash content, sulfur content, phosphorus content, to some extent the heat of combustion and some technological properties of coals are determined by paleogeographic, facies conditions of formation of the coal seam. Formation of coals with abundant water and stagnant regime often predetermines lower ash content and higher sulfur content of coals, higher degree of decomposition of plant residues in comparison with coals formed under water shortage or in moving water environment. The facies conditions of accumulation of the parent material of coal are often associated with its enrichment with rare elements. Obviously, in industrial grouping it is important to take into account the genetic conditions of formation of coal seams.
