  • Probabilistic approach for open pit bench slope stability ...

    The geotechnical slope design of an open pit wall starts at the bench scale configuration. At this scale, the rock slope stability is governed primarily by the geological discontinuities within the rock mass and as a result, structurally-controlled failures (e.g. planar, wedge or toppling) are most likely to occur.
