“…The orebody is sub-vertical, and is exploited using the long-hole mining method. Mining is planned to take place in two phases, the first one between the depths of 80 and 650 m, and the second phase between 650 and 1400 m (Lajoie 2013). The Éléonore project is highly mechanised, and the hauling drifts and the draw points have a typical cross section of 5.5 × 5.5 m.…”

Discrete fracture network based drift stability at the Éléonore mine

Photogrammetry tools were used to characterise the rock mass structural regime at selected mining drifts at the Éléonore underground mine in Canada. This information was used to provide the input data for generating a series of discrete fracture networks (DFN) models. The generated DFN models were subsequently used to investigate the creation of rock wedges along the drifts that may impact the stability of the excavations. The impact of the choice of employed DFN model on the analysis was investigated with reference to the stability of excavations. A series of parametric analyses demonstrated the sensitivity of the model to variations in the properties of the structural regime. The benefits of using stochastic modelling to capture the inherent variability are reviewed.
