Geotechnical services across the mine value chain
Four colour-coded disciplines, one integrated team. Each colour on this site marks the same discipline wherever it appears.
Underground rock engineering
Underground rock engineering
Excavation stability from development ends to large chambers, across narrow tabular, cut-and-fill, bord-and-pillar, room-and-pillar, SLOS and caving methods.
- Excavation, stope, pillar and chamber stability assessments
- Stope design, dilution and over/underbreak analysis
- Ground support design, optimisation and QA/QC
- Rehabilitation of deteriorated excavations
- Sub-level caving, void paste filling and cavity stability
- Fall-of-ground risk management and investigations
- Seismic and rockburst risk assessment
- Raise-bore excavation design and stability
- Ground Control Management Plans, TARPs and SOPs
Open pit and surface geotechnics
Open pit and surface geotechnics
Slope design and management for pits, highwalls, dumps and leach pads, including the transition from open pit to underground.
- Pit slope and highwall stability
- Bench and inter-ramp design
- Limit-equilibrium and probabilistic analysis
- Slope monitoring strategies and radar deployment
- Box cut and strip risk assessment
- Waste dump and leach pad stability
- Open pit to underground transition studies
- Blast vibration monitoring and structural response
- Surface cracking, subsidence and structural damage investigations
Tailings and backfill engineering
Tailings and backfill engineering
From tailings characterisation to backfill strength targets and plant concepts, integrated with the mine plan.
- Tailings facility geotechnical assessments
- Tailings re-mining geometry and stability
- Tailings material characterisation
- Cemented paste, hydraulic, rock and engineered fill
- Mix design and binder optimisation
- Rheology, water demand and pumpability
- Fill strength (UCS) requirements and sequencing
- Backfill plant and reticulation concept support
- Backfill placement and performance QA/QC
Modelling, planning and risk
Modelling, planning and risk
Numerical analysis and risk assessment that feed directly into mine planning decisions.
- 2D and 3D finite element and limit-equilibrium modelling
- Stress, deformation and sequencing analysis
- Rock mass and structural model development
- Geotechnical risk registers and risk-based design
- Geotechnical inputs to short, medium and long-term plans
- Mining method and cut-and-fill optimisation
- Pillar extraction and capital project support
- Pre-feasibility study inputs
- Operational technical services and governance
