3D geological models can be very useful in many geological, mining and other engineering activities. Constructed model should serve as a 3D geodatabase for variety of input data. Study area represents one of the bauxite bearing sites, CrveneStijene, near Jajce. During long time of research and exploration, a number of diverse geological, geodetic, mining and other data were collected. Presented methodology includes the integration, digitalization, organisation and visualisation of different types of input data (600 boreholes, geological maps and sections, DEM, structural measurements from the surface and in the tunnels and adits) in the 3D geological database. In the modeling workflow, different types of geological objects were modeled with different interpolation algorithms. Used interpolation algorithm depends on complexity ofgeological object, character and spatial distribution of input data. The model is interactive which is important because there are constantly ongoing research and exploitation activities: boreholes, underground mining objects, etc. that can be easily imported into the model. 3D geological model represents a basis for planning new research and mining activity.
