Evaluation of stability of slopes is an important part of open pit mines planning and design due to economic and safety considerations. Slope failure can cause disruption to mine operations, loss of lives and damage to equipments. The different kinds and origins of discontinuities play a dominant role in the failure of rocks and hence in mine slopes stabilities. In this paper, the effect of mechanical properties of discontinuities on these phenomena is investigated. Angouran lead-zinc open pit mine is situated app...

The mineral projects have a number of characteristics that make them somewhat different from other types, including the usual long-lived nature of the operation, the pronounced cyclical nature of mineral prices and so on. These increases the risk of mining ventures compared to other types of investment opportunities. Thus this paper has been prepared to presenting the methodology and application of Monte Carlo simulation technique as used in the evaluation of mineral projects to analyze and measure risk. The objec...
