Reliable reflection of geomechanical properties of the rock mass in different areas of a quarry or mine is an important factor for safe and efficient mining design. As a rule, at the development of a mine it is impossible to fully study the site and determine geomechanical characteristics of the rock mass. Therefore, it is extremely important to model the spatial variability of geomechanical properties of a rock mass using limited data. Modern computer software products (Datamine, Micromine, Leapfroge tc. make it possible to processinitial numerical, text and graphic data and obtain digitalt hree- dimensional models of deposits. The standard method of geological modeling consists of interpreting and building a wireframe model for one profile of borehole data at a time, which is time consuming. Modern computer software (Datamine,Micromine, Leapfrog, etc. ensures data processing in severalhours with greater accuracyand considering several geological interpretations that may correspond to theinput data. As a result, geological interpretation using new software tools requiresexperience in the field of geology. The paper covers the stagesof building a three-dimensional geomechanical block model (BM, which takes into account the heterogeneity of geomechanical properties as examplified in one of the iron ore open pits of Rheep ublic of Kazakhstan. It contains the building algorithm of the geomechanical BM, which includes the import and preparation of initial data in the GMIS environment, their visualization; modeling of lithology data and structural trends to aggregate them into domains and interpolate the rating data of the rock mass quality and geotechnical characteristics.
