GAINING DATA ON INACCESSIBLE UNDERGROUND SHAFTS AND PASSES
Finsch uses orepasses and underground silos to transfer ore between levels or to redirect ore for load and haul to the surface. Blockages, hang-ups, overbreak or scaling can impact the structural integrity and result in extended downtime and significant remediation costs.
Accurate imagery enables mine engineers to gauge the integrity of ore passes and plan timely and cost-effective rehabilitation programs. Historically, however, scanning and mapping inaccessible shafts and voids has been a challenge for Petra.
The company’s management sought a means of obtaining accurate visualizations of underground voids, quickly and cost effectively, without endangering the safety of Petra personnel or contractors.
