Optimal pitwall profiles to maximise the overall slope angle of open pit mines

This paper has recently been presented in the SSIM (Second International Slope Stability in Mining Conference) 2021 in Perth, Australia.

The overall slope angle (OSA) of pit walls plays a crucial role in the financial return of open pit mines. The paper showcases a novel design methodology where non-planar geotechnically optimal pit walls with an OSA steeper than what is used in current design practices are employed without compromising mine safety, i.e. the optimal profiles are featured by the same Factor of Safety (FoS) than their traditional design counterparts.

GEOVIA Whittle and Surpac are utilized for this study. You can download the full paper from here or attached.
