Our model results are an end point in the process of data collection, geotechnical domaining, statistical analysis, appropriate rock mass model parameters and yield mechanism selection. It is a synthesis of all the data we collect to forecast rock mass performance and is then the starting point for calibration by taking multiple rock mass observations and assessing against model stages.

Numerical Solutions for Informed High Value Decisions - MineGeoTech

We promote the use of 3D Geotechnical Modelling

Data Collection

Rock mass logging by domains, intact strength properties, structural orientations from acoustic televiewer and hydrogeological investigations.

Numerical Modelling - rock testing - MineGeoTech
Numerical Modelling - ATV OTV - MineGeoTech

Data Analysis

Statistical description of geotechnical domains for probabilistic stability analysis.

Numerical Model

Incorporate the collected data with the mine design voids and loading conditions e.g. seismic/blasting, ground water and stress.

Overall Outputs

With an integrated stream of data from geotechnical core logging, and statistical distribution of input parameters, we use the Hoek-Brown criterion to define the rock mass strength using triaxial strength data downrated by the Geological Strength Index (GSI). This culminates with 3D inelastic finite element numerical modelling.
