Relationship of the parameters of physico-chemical and sorp-tion processes with the emission of coal beds. part I: on the influence of physical and chemical parameters of natural coals on their metane capacity

Abstract

This part of the article shows shows that methane capacity is closely related to the physicochemical properties of coals and the physical structure of coal matter: porosity, moisture, ash content, petrographic composition and the release of volatile substances. It was found that the porosity of natural coals weakly depends on the stages of metamorphism and its effect on the methane content of coals can be ignored. Based on the catalogs of the physicochemical properties of coals from the developed deposits of Kuzbass, it is shown that differences in ash content and moisture content of coals have very little effect on their me-thane capacity, and the main strongest influencing factors on the methane capacity of coal were the depth of coal seams and the release of volatiles.
