Open pit slope stability is a major concern in any mine prefeasibility study. Most widely used numerical and limit equilibrium methods require two inputs: rock mass mechanical parameters and bedding geometry of lithological units. Traditionally, rough geological models prepared by time consuming explicit method of manual digitization or assumptions depending on lithological drillhole logs form the basis for geometry of stability analysis models. However, the real geometry can be dramatically different. A novel method named as implicit modelling is capable of creating solid volumes for lithological units within a few minutes, free of operator bias. Also, complex geological structures like bedding and folding can be represented with high accuracy. In this paper, theoretical background of implicit modelling is covered briefly and a sample application is presented on an open pit iron mine slope stability analysis. Advantages of the geological model prepared by the new method in geotechnical studies are clearly declared.
