Further Development in Engineering Geologic Mapping of Coal Reserves Based on Quality Levels

Resumo

The approach to further development in engineering geologic mapping of mineral reserves with respect to quality levels based on geoinformation models of deposits is substantiated. The algorithm and methods for delineation of clusters in the area of a seam using a vector index composed of simple indicators characterizing useful and harmful properties of coal are explicated. The results of new software trial are presented in the form of distribution of coal reserves for coking and power generation by quality levels and visualization of delineated clusters by means of plotting quality maps.
