Webinar - Optimal pitwall shapes to maximize financial return


Optimal pitwall shapes to maximize financial return

The Overall Slope Angle (OSA) of pitwalls plays a crucial role in the financial return of an open pit mine. In current practice, pitwall profiles are designed to be planar in cross-section within each rock layer, i.e. the profile inclination across each layer tends to be constant. The presentation will showcase a novel design methodology where non-planar pitwall profiles of optimal shapes - i.e. the shape of the pitwall is chosen such that resistance against landsliding is maximised - are employed so that OSA of up to 5 degrees higher can be achieved.
