The article presents the results of developing a methodology for evaluating the quality indicators of minerals based on block modeling technologies using modern miningand geological information systems (GGIS). A flowchart for modeling quality indicators of mineral resources is proposed and the results of its use are shown on the example of the Serov complex ore and coal deposits of the Odegeldey section. The presented method of block modeling allows us to zone technological types and grades of ores with high confidence in the quarry space, which contributes to solving the problems of design, planning and production management in the conditions of economic uncertainty, deteriorating mining and geological and mining and technological conditions for the development of deposits.
