In this open pit mine case the 2D factor of safety is 25 percent lower than the 3D factor of safety because the 3D geometry of the failure surface acts to constrain movement. This cannot be taken into account with 2D analyses. If in this case we were to rely on the 2D calculation of stability as a forward calculation, then we would err on the conservative side. However if this slope failure ...
