By its nature, rock engineering is subject to a great deal of uncertainty and variability, which needs to be taken into account in the design process and in the management of rock-related risks. Variability is a property of nature and is a measure of the change in rock mass Read more... about Dealing with uncertainty and risk in rock engineering design

With the increased drive towards deeper and more complex mine designs, geotechnical engineers are often forced to reconsider traditional deterministic design techniques in favour of probabilistic methods. These alternative techniques allow for the direct quantification of uncertainties within a Read more... about A Comparison of Traditional, Step-Path, and Geostatistical Techniques in the Stability Analysis of a Large Open Pit

In operational open pit mines, large rock surfaces are exposed daily and hundreds or thousands of new discontinuities are exposed, all of which may results in the formation of unstable keyblocks and wedges. It is impractical to attempt to map each discontinuity and carry out a stability analysis Read more... about Bench Berm Design Using Probabilistic Keyblock Analysis

Probabilistic methods combined with risk assessment are a better way to assess slope design in open pit mines compared to deterministic methods. These methods are suitable for use on evaluation of risk or when there is uncertainty in the input parameters.
