Round Hill open pit
A pit slope failure at an operating gold mine was well documented. The failure was controlled by faults that were mapped, and able to be modelled in Leapfrog®. The various surfaces that were required for a slope stability model were exported from Leapfrog® and loaded into TSLOPE. 3D and 2D analyses were carried out, as well as back-calculation of shear strengths that applied at time of failure.
