OVERVIEWThe analysis of slope stability in open pits has been a subject of interest in recent years. The push from industry is to go deeper and be more effective in terms of open pit efficiencies. Allowing deeper open pits is limited by the use of 2D slope stability analysis methods which do not consider the 3D irregularities of actual pit wall design or the possible influence of complex geology, faults, and/or fractures. 3D slope stability modelling has the potential to improve the numerical modelling methodologies associated with the analysis of open pits. This course will look at recent research in the area and its application to the analysis of open pit sidewalls. Particular focus will be in the areas of:

• Design of the conceptual model with improved techniques such that more complex real world scenarios can be represented

• Searching techniques to find a critical slip surface

• Searching for critical slip surfaces with complex geometry and faults

• Use of anisotropic linear models (ALM) to represent the constitutive behaviour of weak planes in rock

The course will compare 2D and 3D methodologies and examine their variations in the light of 3D site geometries. Current state-of-the-art methodologies for the modelling of 3D slope stability for open pits will be covered.

ATTENDEE REQUIREMENTSDelegates are to bring a Windows-based laptop to run the course software. A necessary software installation image will be provided ahead of time, as well as license keys. Laptops should be no more than three years old.REGI

2D/3D SLOPE STABILITY ANALYSIS FOR OPEN PIT MINES SHORT COURSE

Dr Fredlund has, over the past 17 years, guided the development of geotechnical software at SoilVision Systems Ltd. He has directed the development of seven software packages covering unsaturated soil knowledge-based prediction systems, groundwater flow, contaminant transport, geothermal analysis, air-flow analysis, stress/deformation, and slope stability. More recent projects have involved the release of the SVSlope 3D limit equilibrium slope stability software package and the development of 1D/2D/3D large-strain consolidation software.

Dr Murray Fredlund President & CEO SoilVision Systems Ltd., Canada

Ken has more than 27 years’ experience in the civil engineering and mining industries as a geotechnical engineer, researcher and consultant. Ken’s areas of expertise include both soil mechanics and rock engineering in the fields of dams, wasteland form management and open pit slope stability. More recently his research interest has been on the application of unsaturated soil mechanics theory to these areas.
