Abstract

Geoinformation technologies of block modeling for assessing the quality indicators of minerals in the conditions of transient processes in mining. V.D. KANTEMIROV, A.M. YAKOVLEV, R.S. TITOV (Institute of Mining, Ural Branch of RAS, Yekaterinburg).

The article presents the results of the development of a methodology for evaluating the quality indicators of minerals based on block modeling technologies using modern Geological and Mining Information Systems (GMIS). A block diagram of modeling the quality indicators of mineral resources has been developed and the results of its practical application at the following fields: Serov complex ores and coal of the Odegeldey section of the AK-Tal field (Republic of Tyva) are reported. The presented method of block modeling makes it possible to zone technological types and grades of ores in the quarry space with high reliability in express mode, which simplifies the solution of problems of design, planning and production management in the conditions of economic uncertainty, deteriorating mining-geological and mining-technological conditions of field development.
