(VIMS) // kushnarpi@mail.ru MODERN METHODS OF RESERVES CALCULATION AND ECONOMIC-GEOLOGICAL EVALUATION OF DEPOSITS OF SOLID MINERALS For reserves calculation and economic-geological evaluation of mineral deposits the most promising directions is the use of geological-mining information systems (GMIS) based on the data of block modeling. Considered the features of traditional resource estimation and block modeling; the necessity of comparing the data of calculations by alternative methods. Analyzed domestic experience of usage of block modeling in the development of the feasibility study and conducting calculation of reserves. The tasks of implementation GMIS in the practice of revaluation and development of deposits are specified. The attention is focused on the relevance of the development of domestic software products whose development requires financial, organizational and methodological support of state institutes and subsoil users.
