Mine Closure - Geotechnical Considerations
Assessing geotechnical stability in preparation for closure and rehabilitation.
Calibre QuadR was commissioned to assess the geotechnical stability of alluvial tailings dam post-closure landforms as part of a major mine closure project.
Our geotechnics team assessed the stability and closure design of 5 ATDs in accordance with the ANCOLD and the clients D5 requirements.
The stability condition of each individual ATDs was assessed under designed water level and seismic events. The outcomes of the assessments were delivered as an interpretive report to address the client’s requirements.
The key project requirements were:
- Review and compile all available geotechnical data
- Assessment of long term structural integrity of the landforms
- Assessment of stability of landforms against the client and ACOLD standards
