The use of geoinformation technologies in economic-geological evaluation of mineral reserves (by the example of κ-MINE GIS)

Today among the existing methods and approaches to evaluation of subsoil resources those implemented in the geoinformation systems (GIS) play an important role. The issues of calculation of mineral reserves, their economic-geological evaluation, creation of an optimum system for field development, environmental issues etc. are main as regards subsoil use.

For more effective making management decisions during the state expert appraisal of materials for economic-geological evaluation (EGE) of fields with different types of minerals it is necessary to consider the experience gained from consideration of each certain field of this type. Economicgeological evaluation (EGE) of mineral deposits is an important stage of works, which is performed at a final phase of field prospecting and directed to determination of a possibility of its further exploitation in current economic conditions.

With the help of the K-MINE geoinformation integrated system it is possible to perform economicgeological evaluation (EGE) of a field with the use of basic means of a geological and surveying support complex for mining operations, and also a module for economic-geological evaluation of mineral deposits.

A module of the K-MINE geoinformation system for economic-geological evaluation of mineral deposits developed in Ukraine by experts of the Research and Production Enterprise “KRYVBASAKADEMINVEST” has been considered. The module represents a universal tool enabling to perform a whole cycle of works on justification of parameters of conditions for mineral raw material, estimation of mineral reserves and calculation of economic indices of development of a field (accumulated discounted cash flow, profitability). The operation of the module as a component part of K-MINE GIS together with the geological and surveying support complex enables to perform a whole cycle of works starting from bringing of all documentation into a digital form and creation of digital models to economic-geological evaluation of a field with the registration of outputs and preparation of reporting documentation.
