Themes:
- Avoiding catastrophic failure through monitoring and containment
- Tailings repurposing that results in a step change in existing tailings volumes
Project title: Safe disposal of tailings in abandoned mine voids
Research team:
Offering to sponsors:
The project offers a new, cost-effective technology that will eliminate concerns about tailing dam stability and chemical leaching on the surface.
Summary:
The proposal is to dispose tailings into mine voids in a safe and environmentally friendly manner. The tailings would be monitored during placement and settlement using new geophysical technology.
Benefit to industry:
Environmental
- Safe replacement of dirt and tailings
- Improves the stability of mine voids
- Avoids subsidence and caving Eliminates potential for surface leaching
Economic
- Reduce or eliminate the cost maintaining tailings dams
- One-off cost of replacement in the mine voids
