ABSTRACT
Stability assessment is then carried out using empirical, kinematic, limit equilibrium and numerical modelling types of analyses. The type of analysis depends on the complexity of the geometry and on the stage in the life of a mine of the pit slope design (e.g., pre-feasibility to detailed design). This design process is represented in Figure 1 and shows the work flow in ordered steps required to reach the final slope design. It should be noted that modelling is part of an interactive process and should be reviewed and calibrated with monitoring data, including the record of pit slope performance for each sector and the reconciliation of the design batter (bench face) angles versus achieved batter and inter-ramp angles.
