Dight %C Online %8 12-14 May 2020 %B Slope Stability 2020: Proceedings of the 2020 International Symposium on Slope Stability in Open Pit Mining and Civil Engineering %X The Kanmantoo Copper Mine in the Adelaide Hills of South Australia was operated by Hillgrove Resources Limited from 2010–2019. This was a steep-walled, 360 m deep, open pit mine that required an extensive rockfall management plan and the installation of significant rock support and rockfall mitigation measures. The adoption of these systems allowed inter-ramp angles of the structurally controlled west wall to be steepened from 45 to 57°, over a height of 300 m. This paper describes the various methods utilised to manage a range of rockfall hazards experienced at the mine including the use of shear pins, drape mesh, attenuator fences, low- and high-energy rock catch fences and mesh/cable strapping. The design, construction methods, associated costs and the performance of the various engineering controls are described. %K rockfall %K steep mining %K rock support %1 Perth %I Australian Centre for Geomechanics %U https://papers.acg.uwa.edu.au/p/2025_54_Hutchison/ %R 10.36487/ACG_repo/2025_54
