Project
Solution
Executed controlled top-down scaling under strict safety protocols.
Deployed a remote-controlled excavator drill for upper face stabilisation.
Utilised custom-designed wagon drills for mid and lower sections.
Installed Self Drilling Anchors (SDA) supported by advanced plant, including the High Reach Drill (HRD) and SuperBoom.
Collaborative engineering between Geovert, MGI site team, and Coffey Engineers to refine technical design.
Project
Challenges
Large-scale failure involving a 5,500-tonne sandstone block.
Need for safe access restoration to a high-value ore body.
Restricted site access requiring innovative drilling and scaling methods.
COVID-19 travel and workforce constraints during project delivery.
Project
Overview
At Koolan Island mine, a major rockfall dislodged approximately 5,500 tonnes of sandstone from the main pit footwall. The failure, measuring 40m x 50m x 1.5m, was caused by an undercutting joint slip and posed an immediate risk to safe operations.
Following a geotechnical review by Coffey Engineers, Geovert was engaged to design and deliver a robust stabilisation strategy, ensuring the mine could safely access and continue extracting premium 63% iron ore reserves.
