Tailings re-mining and geotechnical assessment

Geotechnical assessment and monitoring support for re-mining an existing tailings facility, integrating geotechnical engineering with mining strategy and operational risk management.

Scope

  • Re-mining geometry and excavation strategy
  • Bench and slope configuration
  • Material and ground conditions
  • Water ingress and groundwater
  • Stability assessment
  • Geotechnical monitoring
  • Risk management
  • Rehabilitation and temporary closure

Underground geotechnical strategy and backfill PFS

Geotechnical and mining strategy support linking ground stability with mine planning, rehabilitation, backfill infrastructure and the production strategy.

Scope

  • Portal rehabilitation and long-term stability
  • Upper-drive rehabilitation
  • Ventilation excavation requirements
  • Historic underground voids
  • Pillar recovery
  • Tailings availability and characterisation
  • Backfill strength requirements
  • PFS-level backfill assessment
Rock engineering and ground control support
  • Underground
  • Platinum mine
  • Bushveld Complex

Rock engineering and ground control support

Rock engineering support focused on converting observations into practical controls that mining crews can implement, with fall-of-ground risk as the priority.

Scope

  • Ground-control risk assessment
  • Fall-of-ground investigations
  • TARP implementation
  • Ground-support compliance
  • Cable anchor and shotcrete requirements
  • Rehabilitation of deteriorating excavations
  • Deformation monitoring
  • Secondary escape-route assessment

Where our experience comes from

Before founding DAQ Geotech, our lead engineer held senior geotechnical and rock engineering roles at major gold, platinum and coal producers, and supported mines across the continent as a ground support specialist.
