Geotechnical Domain Model Evolution During the Mining Project Lifecycle

Anton Bloem, Wayne Barnett - October 2022

Publication - Presentation

Knowing what the representative physico-mechanical properties of a rock mass are at any point in time, is required for successful rock engineering. These properties are commonly represented in the “geotechnical domain model” format.

Foundation Failure in Open Pit Slopes

John Isaac Kwofie - August 2022

Publication - Presentation

Slope failures generally occur because of kinematic instability, when stresses within the slope exceed rock mass strength or both. However, in some situations where ground profile anomalies occur, conventional mechanisms outlined above may not explain the cause of failure.

Building Useful Geotechnical Models

Ian de Bruyn - October 2021

Publication - Published Paper

The success of any geotechnical design is dependent on the geotechnical model used in the design assessments. This paper discusses the conception and development of appropriate geotechnical models for slope design.

Influence of Particle Size-Shape Correlation on the Shear Strength of Scaled Samples of Coarse Mine Waste

Sandra Linero - May 2020

Publication - Published Paper

Technical presentation that describes the importance of particle shape quantification in soil classification and its consideration in activities such as sampling, sub-sampling, and scaling of coarse materials for geotechnical testing.
