Estimation of the Error in the Calculation of Mineral Reserves Taking into Account the Heterogeneity of the Geological Space

Abstract

For effective application of the method of analogy in the geometrization and prediction of indicators, it is necessary to observe the principle of similarity of the field being studied to the field-analog developed by the development. Under the conditions of similarity, it can be assumed that the nature and intensity of deformation of rocks in the conduct of mining operations will be about the same. When choosing a mine-analogue should be based on the coincidence of the degree of metamorphism of coal and rock epigenesis, tectonic structure of the sites, the lithological and material composition of rocks and their physical and mechanical properties, power and depth of the coal seam, hydrogeological conditions. Homogeneous areas of the deposit can be distinguished by various methods of cluster analysis. The quality of the classification is assessed by comparing the average values of indicators in individual clusters (homogeneous areas) with their average values throughout the place.

Machine Learning—A Review of Applications in Mineral Resource Estimation

“…Mineral reserve estimate establishes the mineable portion of a resource and forms the foundation for economic anaslysis of a mineral deposit as well as the future potential of an operating mine. The accuracy of a reserve estimation is essential to the quality of the geological interpretation [13,14]. It is also vital to mine planning and design, including the utility of short-term and long-term mine plans.…”
