Abstract

The real time geotechnical monitoring systems for assessing the open pit mines slopes stability had a rapid evolution over the last few decades. Due to their potential to advance the safety of the open pits’ operations, and based on the additional confidence that operators gain from instantaneous access to the information, these technologies can change the mine planning parameters, especially for activities taking place adjacent to the sensitive public infrastructures and increase the overall safety of mining operations. This presentation will update on the experience of a Canadian coal mine operating in the rugged topography of the Alberta foothills, excavating extremely structurally complex coal deposits within thrust and fold belt geology. One case study that involved an open pit footwall failure is presented. Back analysis of all the failures from the monitoring data can refine the understanding of the speed the failures progress at, and generate the best metrics and thresholds to define how alarm systems should respond to the slope deformation.
