Pit slope topography, as modelled in TSLOPE.ДЄs a check, we draped the surface geology sketch on our model of the pit slope (Figure 4).ДЇigure 4. They were loaded directly into TSLOPE (Figure 3).ДЇigure 3. The ground surface prior to slope failure was available as a gridded file with x, y, z coordinates. The modelling process enabled us to use the structural information from the geological mapping (dip and dip direction), and follow the outcrop pattern of the faults so that the modelled surfaces reflected the irregularities of the fault surfaces and were not approximated as simple planar surfaces. In this case, the four fault surfaces were modelled using LeapfrogВ®, and the surfaces were imported into TSLOPE using the.

TSLOPE relies on the user having access to a software package that is able to model surfaces. The Bag Farm Fault on the western side dipping to the east the Back Fault at the top of the slope, dipping south the Linking Fault on the east side, also dipping east the base of the slope failure was controlled by the Incipient Fault with a shallow dip to the west. The four faults that controlled the slope failure are shown. Geological sketch map of slope failure area. A geological map of the area was available, as shown on Figure 2.ДЇigure 2. Geological mapping of the pit face showed that the rock mass involved with the failure was bounded by four faults. We show by our study of this open pit mine failure that there can be a significant difference between factors of safety calculated using 3D and 2D analyses. Stability analyses can also be carried out in 2D, using arbitrary sections drawn across the 3D model. The failure surface can be any shape, such as formed by interconnecting fault surfaces as in this open pit mine failure. TSLOPE is able to carry out 3D limit equilibrium analysis of columns overlying a shear failure surface. We have taken the relevant data, and developed a three dimensional slope model using TSLOPE, an innovative software package for slope stability analysis. Photograph of pit area involved with slope failure. The failure as shown in Figure 1, involved three benches at an intermediate slope that was being pushed back towards the final high wall location.ДЇigure 1. In 1996 a slope failure occurred at the Round Hill open pit mine, operated by Macraes Mining Company Ltd.
