| Abstract: | The stability of an opencast mine slope, investigated by the limit equilibrium method, indicates that 148m deep open pit is stable with 60° overall slope angle. Geotechnical mapping was undertaken to determine the critical orientation of structural discontinuities. Geomechanical properties were determined in the laboratory and subsequently modified to approximate those of in situ rock mass. Sensitivity analysis was done to determine the influence of the slope design parameters on the safety factor. It was also used in determining the most suitable remedial measure for the critical slope. Slope monitoring did not reveal any movement in and around the pit. |
