Abstract (summary): A thorough understanding of in-situ rock mass geomechanical properties is a key factor for a safe and efficient design of a mining project. Geomechanical properties in a mining project are generally quantified using sample data collected during site investigation. In many mining projects, an exhaustive site investigation to characterize the rock mass properties is impossible. Hence, it is crucial to model the spatial variability of rock mass geomechanical properties using the limited data. This thesis proposes and implements geostatistical simulation approaches for modeling of geomechanical heterogeneity of the rock masses in an iron ore open pit mine. 3D block models for geomechanical properties in different pit areas are generated and verified using statistical methods. The 3D geomechanical models allow the heterogeneity of rock masses to be involved in open pit mine planning and design, as more accurate knowledge of spatial distribution of geomechanical properties promotes safe and economic mine operation.
