mine closure and support

Closing Time

Pacific West has closed numerous Abandoned Mine Lands (AML). Our teams are trained in every aspect of mine closure and support (AML). With precise solutions that work around obstacles, we’ve completed projects across a range of geographic locations. We even work where there’s difficult or minimal access, building our own materials on-site and modifying techniques to protect the environment, inhabitants, and human health.

safe decommissioning

Mine closure is a critical phase in the lifecycle of mining operations, and Pacific West excels in managing this process. Our experienced team works closely with mining companies to develop and implement closure plans that adhere to industry best practices and regulatory requirements. These plans include the safe decommissioning of equipment and infrastructure, reclamation of disturbed lands, and the establishment of long-term monitoring and maintenance programs to mitigate environmental impacts.

Happy Land = Happy clients

Try the clients who come to us for AML assessment and closure services—the US National Parks Services, the US Forest Service, the Office of Surface Mines, the Bureau of Land Management, and the Arizona Department of Environmental Quality to name a few. Our reputation and excellent work continually make us the preferred contractor for companies and agencies.



how we tackle mine closure

  • Signs that prohibit access to AML sites with public safety hazards.
  • Fences ranging from three strand wire fences to chain-link.
  • Steel wire or cable nets for treating large mine openings.
  • Earthen backfills that fill open voids; a best practice when wildlife habitat or historic significance are not primary considerations.
  • PUF – Polyurethane foam plugs that go along with earthen backfill, and let us plug large holes with a small amount of material.
  • Rock or concrete barrier walls for horizontal mine entrances.
  • Steel gates and grates with lockable hatches that allow access.
  • Wildlife-accessible steel gates and cupolas to allow free movement of important wildlife species like bats and desert tortoise.
  • Reclamation that stabilizes terrain and returns it to its approximate original contour.
  • Returning land to standards of public safety, aesthetic improvement, and useful purpose.
