Abstract: In recent years, an innovative approach has been proposed in using two ground-based synthetic aperture radars to simultaneously monitor slope stability (Severin et al. 2011; 2014). The technique allows to obtain a detailed pseudo 3D displacements map covering large pit slopes. In October 2014, a similar experiment was conducted at MMG Limited’s Century Mine (Queensland), using two real aperture radars. The outcomes of the test have shown that even if reasonable results can be achieved, more precise information can be obtained through the integration with prism data. The technique has produced a much clearer image of the slope deformation, identifying a complex break-up of the slope surface due to the weathering process affecting the shale rock mass.
