Abstract

An analysis of the requirements of the national classification of mineral resources for the mandatory use of quantitative and probabilistic methods in assessing their reliability has shown that the existing methodological support does not fully meet the state of the coal industry and trends in the development of methods used in international assessment of the confidence of mineral resources. Taking into account the accumulated Russian and international experience in the procedure for classification of mineral resources and the current requirements of investment mining projects, the Methodological Recommendations for the Quantitative Assessment of the confidence of coal resources have been significantly revised, expanded, and presented in a new version.

Keywords

Classification of mineral resources, categories of mineral resources, confidence of mineral resources, quantitative methods, methodological support.
