Analysis for Geotechnical Design
Quantifying the interaction of implicitly-modelled 3D solids and surfaces with working pits and pit designs, to highlight areas of potential instability

Assessing and quantifying the interaction of geological features, such as bedding, foliation, contacts, faults and major fracture, with a mining surface, Whittle shell or pit design is essential for geotechnical design and planning
Fully-constrained, implicit 3D geological models, which intelligently incorporate downhole structural data from macrostructural logging, geophysics and A/OTV, significantly improve the resolution and geometrical realism of these features
TECT utilises several software packages to extract and quantify the geometry of features, in 2D or 3D data grids, which are then projected onto any intersecting pit or design surface, following which apparent dip and conditional shear-failure are analysed as spatially-continuous parameters
Geotechnical block models of these parameters are also generated. Results are plotted as either discretized or contoured maps, which allow Geotechnical Engineers to identify and monitor potentially unsafe areas, or to optimize pit slopes and inter-ramp angles
This supplements and greatly improves traditional analyses along radial 2D design sections, which use medians or means for critical angles
