Verification of a Large Scale Slope Instability Mechanism at Highland Valley Copper

Open pit numerical model calibration using a pseudo three-dimensional radar monitoring technique

“…The data and results from this experiment demonstrated that pseudo-3D vectors could be https://papers.acg.uwa.edu.au/p/1308_42_Severin/ created from the two radar data sets and that the information could be used to investigate slope kinematics in areas without geodetic monitoring points as well as an increased ability to review the displacement response to open pit mining over an entire slope. This paper extends the initial analysis previously completed by Severin et al (2011) and builds on previous slope kinematic models created to describe the observed displacements (Rose and Scholz, 2009;Tosney et al, 2004). Information gained from the monitoring data was then used to create and modify a pit wall scale discrete element model of the Lornex Pit.…”

Development and application of a pseudo-3D pit slope displacement map derived from ground-based radar

“…Review of the combined radar displacement data (magnitude, direction, and plunge) allows for an expansion of earlier slope kinematic models (Tosney et al, 2004;Piteau Associates Ltd, 2008;Rose and Scholz, 2009), which were created to describe the observed displacements within the Lornex Pit based on field observations and geodetic data, complemented by 2-D numerical analyses.

Influence of tensile strength on toppling failure in centrifuge tests

“…Column at toe Remaining columns Joint persistence ratio k 0. modelling approach used by [8,6,7] to simulate toppling. The conventional UDEC numerical model used in this study was generated with the same geometry shown in Fig.…”

“…Hence the modelling of toppling slopes, involving discontinuous joints, must provide for both shear and tensile failure through intact rock bridges and for slip along existing joints. Modelling of the toppling process is often attempted using discrete elements with throughgoing fractures that form both the sub-vertical layers and the cross-cutting sub-horizontal fractures [6][7][8]. Using this approach, the movement kinematics are defined by the geometrical constraints built into the model.…”
