Mine Subsurface Investigation

Key task activities performed:

• Developing profiles, and identifying subsurface anomalies, weak or collapsed (rubble) zones, intact pillars, and the extent of mine voids and their respective orientations at various mining levels.
• Conducting void imaging surveys using borehole deployable robotic laser scanner- Creating 3D laser models, and determining void sizes and volumes.
• Determining the subsidence mechanism and related failure modes.
• Assessing subsidence and sinkhole risk levels.
