Expert hydrogeological input to support the mining lifecycle
BGC’s approach to supporting mining projects with groundwater challenges and opportunities begins with an understanding of the site geology. From baseline and environmental assessments to pre-feasibility, feasibility, detailed design, and permitting expert hydrogeologic input is required. We also support the construction, operations, and closure of mining projects, guiding clients through all stages of the mining lifecycle.
Our team conducts detailed site investigations to understand both site geological and hydrogeological conditions, which we use to develop and refine conceptual hydrogeological models. Depending on project needs, our experts then develop analytical or numerical models to:
- Assess potential impacts on the hydrologic (groundwater and surface water) system and neighbouring environments
- Develop water balance models, water quality models, and water management plans
- Design open pit and underground depressurization and dewatering systems
- Evaluate tailings seepage containment and management options
- Evaluate the potential for water supplies and establish protection zones.
We support permits to take water applications, review and optimize groundwater management plans, and evaluate the hydrogeological regime as part of reclamation and closure planning. BGC hydrogeologists, hydrogeological engineers, and geotechnical engineers evaluate porewater pressure and seepage associated with slopes, highwalls, and dams; we design and install dewatering and depressurization systems, design groundwater remediation systems and install seepage interception systems. We 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.
