Bench scale open pit slope failures are common occurrences in open pit mines and present a hazard to workers near freshly excavated faces. Objectively forecasting the zone of influence of bench scale failures is an important component of the mine’s

Rock avalanches involve extremely rapid, flow-like movement of fragmented rock with extreme destructive potential. With increasing development pressures in mountainous regions, there is a need for simple, stochastic estimates of runout distances to a

SSIM 2021: Second International Slope Stability in Mining.
Open pit slope designs are often controlled by persistent or pervasive discontinuities in a rock mass. Whether a discontinuity will be important for inter-ramp and overall scale assessments is difficult to ascertain, especially for development projec

Proceedings of the 2020 International Symposium on Slope Stability in Open Pit Mining and Civil Engineering.
A Fahrboschung angle versus volume methodology for estimating the runout distance of large open pit slope failures was proposed to the open pit geotechnics community in 2015 (Whittall et al. 2015). Since that 2015 publication, three commonly received

The high consequences of recent large open pit slope failures have increased industry and regulatory interest in establishing exclusion zones beneath an impending pit wall failure. This paper proposes a methodology to delineate an exclusion zone for

Objectively forecasting the runout of a potential open pit slope failure, in addition to identifying the failure itself, is a critical component of a mine’s risk management plan. Recent losses arising from large open pit slope failures demonstrate
