. The article presents the results of developing the procedure of evaluating quality indicators of minerals based on the technology of block modeling with the use of modern mining and geological information systems (MGIS). The flowchart of mineral quality indicators modeling has been proposed, and the outcome of its application has been presented by the example of Serovsky complex ore deposit and Odegeldei coalfield, the Tyva Republic. The presented procedure of block modeling makes it possible to zone the industrial types and sorts of ore in the open pit with a high degree of accuracy, which helps to solve the problems of industrial design, planning and management in the conditions of economic uncertainty, deteriorating mining and geological and mining-process conditions of field development. Research aim is to develop a universal algorithm of block modeling to improve the procedures of evaluating quality indicators. Methodology. The scheme has been developed which establishes the connection between the stages of modeling and process solutions for field opencasting. Based on geologic feature block modeling, the procedure of mineral quality indicators geometrization has been widened and improved. Results. The flexibility of mineral quality block modeling procedure has been proved. It can be applied at any deposit to solve certain mining engineering objectives. Based on the presented scientific results, mineral quality control procedures may be developed, and mining planning may be improved in the mode of quality control. Summary. The proposed methodology is flexible and makes it possible to evaluate quality indicators of minerals to select rational techniques of mineral quality control.
