Description
Summary:It is not possible to determine the type of coal in terms of reducibility from thermal decomposition without access to air for volatile maters to dry ash-free mass, which provides establishing the ratio between oxygen content and other essential components of organic mass. The hazards of coal mine operations depend to a large extent on the ratio of the main components, both in organic matter and in mineral impurities. Methods for determining the yield of volatile maters make it impossible to assess the effect of the main components of organic matter and mineral impurities on the hazard characteristics of coal seams. The volatile maters index reflects only the sum of the thermal decomposition gases: hydrogen, methane, carbon monoxide and carbon dioxide without considering the ratio between them. The determination of the hazard properties of a seam in relation to metamorphic transformations factor should include a case-by-case examination of the relationship between the major components of fuel both the organic and mineral, including the moisture content, for each coal seams.
