Services
Geomechanics and underground works
RMR, Q and GSI characterization, 3D geomechanical models, pit slope, tunnel and ground support design at every project stage.
Our team assesses foundations, pit slopes and underground works at conceptual, pre-feasibility, feasibility, detailed design, construction, operation and closure stages.
Service scope
Surface geomechanics
- Supervision and logging of vertical and oriented diamond drilling, at surface and underground.
- Core orientation using ACT II/III, Devicore and optical and acoustic televiewer methods.
- In-situ permeability testing, and installation and monitoring of Casagrande and vibrating wire piezometers.
- Geological-geomechanical and structural mapping, and geological fault inventory.
- Detail lines and geomechanical stations with RMR76 and RMR89 classification, Barton's Q index and GSI estimation.
- In-situ tests on outcrops and core (Schmidt hammer and tilt test) and on residual soils and quaternary deposits (pocket penetrometer and vane).
- Planning of rock and soil mechanics laboratory testing at certified institutions.
3D geomechanical modeling
- Block models of geomechanical properties (RMR, GSI, RQD, Barton's Q and strength).
- Interpretation of 3D lithological, alteration and structural geological models for geomechanical assessments.
- Application of model results to pit excavability and blasting.
Underground design and stability
- Rock mass geotechnical model built from geological, structural and hydrogeological models.
- Geomechanical characterization and zoning with RMR89, RMR76, Q, GSI and MRMR systems.
- 2D limit equilibrium and 2D/3D finite element stability analyses.
- Geomechanical tunnel design and ground support specifications.
- Geomechanical models under high-stress conditions in deep underground workings.
- Geotechnical instrumentation and monitoring.
- Trade-off, pre-feasibility, feasibility, basic and detailed engineering studies.
