Shebandowan Mine Dam Safety

Project Overview
Location: Thunder Bay, ON
Client: Vale
Services: Engineering, Geotechnical & Dam Engineering, Environmental
Sector: Mining
Project Description
Vale's Shebandowan Mine site northwest of Thunder Bay includes multiple water-retaining and stormwater management structures associated with the former mining operation. TULLOCH completed a Dam Safety Review covering six tailings dams, one spillway, and one mill stormwater runoff management pond.
The assignment combined data review, field investigation, instrumentation, dam-safety analysis, and failure-mode assessment to evaluate the condition and performance of the impoundment facilities and support ongoing risk management.
As part of a separate scope, TULLOCH provides coordinated technical and field environmental support that helps Vale manage risks and meet ongoing regulatory requirements.
Scope of Services
- Data collection and review
- Geotechnical investigation and instrumentation installations
- Dam Safety Review analysis and evaluation
- Failure Modes and Effects Analysis
- Mine care and closure inspections, sampling, monitoring, reporting, and contract administration
