Abstract/Summary The Ridgeway Deeps Block Cave mine is owned by Newcrest Mining Limited and is located near Orange, NSW, Australia. The block cave extraction level is located at a depth of around 1114 m, and is 210 m directly below the existing Sub-Level Cave. During cave establishment, extensive rock mass deformation data was collected on the undercut and subsequently analysed using numerical, analytical and empircal methods. The data consisted of underground observations, convergence and extensometer measurements, and micro-seismic data. This information was used to make key tactical decisions during undercutting, in particular mitigating or managing operational impacts relating to deformation, damage and seismicity. This paper defines key aspects of the methodology used for understanding drive deformation and the measured response in the three rock types traversed by the advanced undercut.
