Slope failures are an inevitable and often an economically attractive aspect of pit slope design in the mining industry. Industry design standards typically accept up to 30% of benches in surface mines to collapse, provided that they are managed so that no personnel are at risk. Too many failures impact on productivity, and larger scale failures ar...

Slope failures are an inevitable aspect of economic pit slope design and execution in the mining industry. Industry standards typically accept up to 30% of benches in surface mines to collapse, provided that they are managed such that no personnel or critical infrastructure are at risk. For larger scale instability, the acceptable limits reduce to...

Slope stability modeling techniques and deformation monitoring technology has significantly improved in the last decades. Three-dimensional modelling is rapidly becoming standard practice for the design and optimization of open pit mines and waste rock dumps. This paper presents a case study demonstrating the use of 3D limit equilibrium analysis fo...
