EXPERT HYDROGEOLOGICAL INPUT TO SUPPORT THE MINING LIFECYCLE
From baseline and environmental assessments to pre-feasibility, feasibility detailed design, permitting, construction, operations, and closure, expert hydrogeologic input is required. BGC’s approach to supporting mining projects with groundwater challenges begins with the development of a good understanding of the site geology.
Once the site geological conditions are well understood, our experts conduct detailed site investigations to develop and refine a conceptual hydrogeologic site model and then develop analytical and numerical models to evaluate the hydrogeological setting for the region and the site. With these models, our experts:
- Design open pit and underground depressurization and dewatering systems
- Evaluate tailings seepage containment and management options
- Develop water balance models, water quality models and water management plans
- Assess impacts to the hydrologic (groundwater and surface water) system and neighbouring environments, water quality models, and water balance models
- Evaluate water supply studies and protection zones
We support applications for permits to take water, design and install dewatering and depressurization systems, design groundwater remediation systems and install seepage interception systems, review and optimize groundwater management plans and evaluate the groundwater regime as part of reclamation and closure planning. BGC hydrogeologists and geotechnical engineers work closely to evaluate pore water pressure and seepage associated with slopes, highwalls and dams. We work closely to evaluate rock-water-soil-air interactions and implications for groundwater and surface water quality during all phases of mine life from baseline pre-disturbance to post closure conditions.
