The Highland Valley Copper mine is one of the world’s largest open pit porphyry copper mining operations. The pits are subject to a slope instability mechanism that resembles a combination of large scale and classical block toppling. Experience has shown that while this type of instability mechanism does not develop into catastrophic failure, slope deformations in the order of tens of metres can occur. The slope instability mechanism is not a pure toppling mode of failure and cannot be adequately analyzed using traditional limit equilibrium methods. In an effort to further develop an understanding of the deformation mechanism, a study was conducted which included detailed field mapping, extensive slope deformation monitoring, laboratory testing and distinct element numerical modelling. The insights gained from these efforts have been combined to develop a design approach that will be applied to future slope design and mine planning for the Highland Valley Copper pit slopes.
