Rethinking the life of a mine

What happens to a closed mine? Instead of simply abandoning a site, mines of today need a closure plan.

Farmland is already cleared of trees and structures. Sometimes it’s used as a temporary mining site. Once the mining is done, agricultural land can be restored and go back to producing food.

Transforming mining lands for beneficial public use is a great option. For example, the Pikeview Quarry is transitioning into a recreation park for the Colorado Springs community.

Pumped storage is a great renewable energy option for open pit mine closure. Learn more about a pumped water renewable energy project in Southern Australia.

Developing green energy infrastructure on a brownfield power-generating site has a satisfying symmetry. Learn more about going from coal to solar in Nanticoke, Ontario.

Our mining and ecological teams restored wildlife habitat by resloping mine waste rock. This project was a big win for the caribou population in British Colombia.

Large swaths of land that were once used for industrial sites can be replanted and become an asset for carbon sequestration. Companies can then measure carbon sequestration via remote sensing.

In Bristol, UK, a historic coal mine site was transformed into new grounds for residential use. Mining professionals mitigate geotechnical and chemical hazards before repurposing it.

An aging mining and metallurgy testing area was transformed into a modern space that incorporates the community’s needs to live, work and play.

Mining companies can partner with traditional landowners to restore and return the land. Learn more about Rio Tinto’s Argyle Diamond Mine and the natural ecosystem reclamation in Australia.

Start with the end in mind

Many mines in operation today are reaching the end of their lifespan. So what happens once an orebody is depleted? In the past, many mines were abandoned. Today, mines must have a closure plan in place before they even begin. A modern approach to mine closure is to appreciate that the mine has given everything it can to us and now it’s entering its next chapter.

Pollinator-friendly solar farms involve planting native shrubs, grasses and flowers beneath solar panels.

Plan ahead for closure

The best opportunity for making impactful closure decisions happens early in the mine’s life. Early engagement aids in community acceptance and mitigates surprises at the end of a project. It also reduces cost and leaves a positive legacy for the community.

If a mine site has not been planning for closure, or was abandoned, site assessment and stability evaluation are the first steps in closure. Overall site stability refers both to environmental—mitigating soil or water contamination, and physical—grading or sloping the ground.

A closed mine deserves to be reborn as something new. A poetic option is to develop a mine site into a renewable energy site, so the land can continue to generate resources.
