Abstract:
The Telfer gold-copper mines in the Great Sandy Desert in the East Pilbara region of Western Australia lie 400 kilometres east-southeast of Port Hedland and approximately 1,300 kilometres by air or 1,900 kilometres by road north-east of the state’s capital, Perth. Telfer comprises the Main Dome and West Dome open pits and the Telfer underground mine. GroundProbe Slope Stability Radars (SSR) are the primary monitoring tool at Telfer open pit mine for managing slope instability risk to personnel and equipment in a steep, brittle, hard rock environment. This paper summarises the results of the back analysis of 15 collapses at Telfer gold mine and presents a discussion of the process developed by Geotechnical Support Services for application of SSR alarms in an open pit mining environment.
