High-resolution 3D geological model of the bauxite-bearing area Crvene Stijene (Jajce, Bosnia and Herzegovina) and its application in ongoing research and mining

Three-dimensional (3D) geological models are useful tools in various geological, mining and other engineering activities. Geological model defines stratigraphic and structural settings of the studied area in 3D virtual environment, and serves as a 3D geodatabase for variety of input data. Chosen studied area is one of the bauxite bearing sites, Crvene Stijene, near Jajce (Bosnia and Herzegovina). During last decades, a number of geological, geodetic, mining and other data were collected through intensive geological and mining research, with the aim of finding and exploiting bauxite deposits. Therefore, selected area is a great polygon for the development of the methodology for construction of 3D geological model and its application in current and future research and mining. Presented methodology includes the integration, digitalization, organisation and visualisation for 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, fault planes and geological surfaces, were modeled with different interpolation algorithms. The constructed model is interactive and it can be easily updated by new input data from current research and exploitation activities: boreholes, underground mining objects, etc. Interactive 3D geological model represents a relevant foundation for planning of new research and mining activities. Furthermore, newly found deposits and their volumes can be quickly modeled, contoured and calculated. Presented modeling workflow is applicable for other areas and other raw mineral resources.
