Results
Complete stabilisation of the highwall, enabling safe resumption of mining operations
Installation achieved with zero lost time injuries, despite the large scale and complexity of works
Provided the client with a long-term stabilisation and monitoring system, reducing risk of future instability
Demonstrated Geovert’s ability to deliver technically demanding ground support solutions within active mining environments
Project
Solution
Undertook comprehensive risk assessments with the client to define safe working methods and technical requirements
Applied a combination of mechanical and rope access scaling to remove unstable material and prepare the face
Installed engineered high-tensile mesh systems across over 6000m² of slope face to contain rockfall hazards
Deployed specialist drilling fleet with advanced rigging techniques to install nearly 1000 ground anchors across the affected zone
Implemented robust documentation, monitoring, and verification systems to ensure compliance with the engineered design
Project
Challenges
Large-scale instability spanning 150m at the crest and 270m at the toe
Vertical height of 180m creating complex access and safety risks
Requirement to work within an operational mine environment while maintaining production continuity
Need for precise installation of anchors and mesh across more than 6000m² of face
Stringent verification and compliance requirements from client and regulators
Project
Overview
A significant highwall instability at a West Angelas Iron Ore operation in Western Australia required the temporary quarantine of valuable ore reserves. The failure 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 design and deliver an engineered stabilisation strategy that would allow mining operations to safely resume in this high-value zone.
