A contribution to financial and geomechanical pit optimisation

Surface mine financial optimisation and geomechanical design are not well integrated. This paper presents a case study where both the net present value (NPV) and the design of slopes, for various ultimate pit scenarios, were assessed based on the geological block model. In the first stage, the stabi...
