Purpose and objectives. Since 2009 the State Commission of Ukraine on Mineral Resources (SCMR) together with the Research and Production Enterprise “KRYVBASAKADEMINVEST” LTD (the city of Kryvyi Rih) performed works on the development of algorithms for calculation of reserves and resources of different types of minerals for the purpose of their transfer from one classification system to another. On the way to harmonization of reserves in different classification systems there is a method based on the use of three-dimensional digital models and special software with further comparison of the obtained results when calculating reserves and resources of mineral deposits in different classification systems. K-MINE GIS is a basic tool used in work.
The basic principles realized in the K-MINE GIS module – Mineral Reserves Economic-Geological Evaluation Automated System (K-MINE EGE AS), which uses approaches generally accepted in the world as regards interpretation of data on prospecting, delineation of ore bodies and mineralization zones, wireframe modeling of a field and surfaces, variography, interpolation of spatial values with the use of geostatistical methods, block modeling, reserves evaluation, have been developed. The majority of operations on interpretation, delineation and wireframe modeling are automatically performed.
Method. Economic-geological evaluation of fields with the use of basic capabilities of the geological mine survey support complex, and also K-MINE EGE AS has been carried out by means of the K-MINE geoinformation integrated system. The module for economic-geological evaluation of mineral deposits is intended for performance of analytical and graphic works connected with the economic-geological evaluation of mineral deposits.
Results. So, when carrying out economic-geological evaluation with the use of K-MINE EGE AS it is possible to use both standard (“traditional”) methods for reserves calculation (cuts methods, geological blocks, etc.), and modern spatial methods based on geostatistical methods with the use of wireframe and block models.
When drawing up the report on reserves calculation according to the CRIRSCO classification the computer models shall be used. It has been demonstrated that K-MINE GIS meets the requirements for computer systems according to the CRIRSCO template.
Practical importance and conclusions. So, the K-MINE GIS economic-geological evaluation module is 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 field development. Operation of the module as a component part of K-MINE GIS together with the geological mine survey 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. When using “traditional” methods for calculation of qualitative and quantitative indices with the use of K-MINE GIS and its automated module it is possible to reach high accuracy and repeatability of results. It is caused by the use of analytical methods for calculation of main geometrical indices of the units of measure (area, distance) and minimization of errors connected with manual information processing.

Keywords: K-MINE GIS, geoinformation system, mineral deposit, economic-geological evaluation, block modeling, CRIRSCO template.
