Slope Stability Analysis a Case of Chingola Open Pit-COP FD

Siwakwi Boniface

Abstract: The factor of safety has been traditionally used as an indicator to assess the stability of the slope. For slopes, the factor of safety F is defined as the ratio of the actual soil shear strength to the minimum shear strength required to prevent failure. There are many factors that control the factor of safety. This includes the presence of water, inherent discontinuities F is the factor by which the soil shear strength must be divided to bring the slope to the verge of failure. In this paper, the factor of safety of the slope COP FD at Nchanga mine is calculated using LEM and FEM and the results obtained compared as a check for consistency
