Abstract. The volatiles yield, taking into account the methods of determination, does not correspond to the classical (commonly accepted) parameter of metamorphism as a composition and properties change of coals in the process of geological transformations of coal seams. One indicator, even the most versatile one, unable reliably and comprehensively distinguish the change of the ratio of all components for the organic matter and its properties under the influence of metamorphic processes. The research methodology is based on the statistical processing of known experimental data obtained from regulatory documents for almost all coal seams of the Donbas and the Lviv-Volyn basin. As an alternative criterion of metamorphism in relation to the volatile release, the carbon content in the organic (combustible) mass of fuel is taken. Selection of an alternative indicator is based on the carbon content indicator has some advantages over the other indicators for prediction of the hazardous properties manifestation of coal seams. According to the correlation tightness between the indicators of the volatile release and the carbon content with the basic elements of the organic (combustible) mass, it was concluded that every of the indicators considered corresponds to a reliable description of a certain aspect of the metamorphic transformations of coal seams. The studies conducted have shown a significant multiple factor influence of metamorphic processes, both on the change of the element compound of the combustible (organic) mass of the initial coal matter, as well as on its physical and mechanical properties. It is not possible to describe such a range of changes for the compound and properties of coals during the metamorphism of coal seams, as it is presented in regulatory documents, by means of a single indicator, i.e. volatile release during coal thermal destruction. This indicates necessity to improve the regulatory framework for the safe conduct of mining operations. While making the necessary corrections, it is proposed to take into account the features of changes established within the element compound as well as properties of coals during metamorphic transformations of coal seams.
Keywords: coal, metamorphism, coal seams, indicators, carbon content, sulfur, combustible mass, mining, safety, regulatory framework, improvement.
