Principles of differentiation of coal deposits by significance

With a large number of reserves and predicted resources of coal in the country, only a part is in demand by external and internal consumers. High competition in the market of fuel and energy resources, changing in time and location, demand and supply for various brands and grades of coal products determine the need for a regular multilateral assessment of the raw material base of existing and established mining enterprises. When implementing investment projects in difficult geopolitical and geo-economic conditions, one of the ways to reduce risks is a comprehensive study and selection of the most attractive fields for rational development. The formulation of the principles of their differentiation according to the level of geotechnological, qualimetric, environmental and investment significance based on the analysis of the applied methodological approaches and their development is updated and determines the purpose of the study. The performed analysis showed that there is a range of different approaches and evaluation criteria of different significance and weight, explicit and not formalized, complementary and contradictory. This makes it possible, given the uncertainty of the market environment, the variety of development conditions, the complexity of the structure of deposits, the heterogeneity of the properties of minerals and rocks, to form various options and their combinations for selection, not excluding conjunctural and lobbying. The order of ranking of coal deposits by importance, balanced from various positions, proposed as part of the development of the digital deposit concept, makes it possible to move more reasonably to their effective development.
