PROJECT OVERVIEW
A significant highwall instability at a West Angelas Iron Ore operation in Western Australia required temporary quarantine of valuable ore reserves. The affected zone extended 150m wide at the crest, expanding to 270m at the toe, with a vertical height of approximately 180m above the pit floor. Geovert was engaged to develop and implement an engineered solution that would enable safe resumption of mining operations in this high-value zone.
PROJECT SOLUTION
Following comprehensive risk assessments in collaboration with the client, Geovert developed and executed a detailed stabilization strategy. The solution integrated multiple technical elements, utilizing our specialized drilling fleet for both ground support installation and monitoring systems.
Our approach combined mechanical and rope access scaling methods, followed by the installation of engineered mesh systems across over 6000m² of the face. The installation utilized advanced rigging techniques to secure nearly 1000 ground anchors across the affected area.
Throughout execution, detailed documentation and verification processes ensured compliance with design specifications. This comprehensive approach enabled complete stabilization of the affected area while establishing robust monitoring systems. The successful delivery, achieved with zero Lost Time Injuries, allowed resumption of mining operations in this previously quarantined area.
