• Numerical Methods for Slope Stability Analysis of Open-pit Mines by Sina Javankhoshdel, Ph.D., P.Eng., Geomechanics Specialist at Rocscience, Canada

Sina provides an introduction to the 3D Limit Equilibrium Method (LEM) and Finite Element Method (FEM) of analysis as the main slope stability methods for open pit mines. He also presents the pros and cons of each method and their differences. A 3D open pit model is also provided in this presentation with the results of both LEM and FEM.

• Loading Rate Dependency in Dynamic Tensile Strength of Brittle Rocks by Ali S. Hashemi, Ph.D., Geomechanics Consultant at RockEng, Canada

Ali discusses the dynamic behaviour of rock material, and different experimental methods he has conducted accompanied with numerical methods to show the loading rate dependency in dynamic tensile strength of brittle rocks…

• Stability Assessment of Initial Shotcrete Lining using 2D Continuum Modeling Approaches by Saeed Naseri,  MASc., Dalhousie University, Halifax, Nova Scotia, Canada

Saeed talks about stability assessment of initial shotcrete lining using 2D continuum modeling approaches. He used two methods for the shotcrete liner stability analysis:

The first one was using the Conventional approach based on CCM which resulted in an LFS less than one

The second one was using support capacity diagrams resulting in an LFS less than one…
