Mine closure: a conceptual review

There are many different words to describe mine closure, including rehabilitation, reclamation, restoration and decommissioning. Closing mining operations, mainly open pit mines, has required resolution of numerous issues. Mine closure plans involve environmental-protection issues, regulatory issues and community issues. The obvious, and often most expensive of them, is the physical rehabilitation of the disturbances and the elimination of long-term commitments and maintenance. This paper outlines mine closure planning and its important component, mine-site rehabilitation. Community consultation and involvement are also referred to as an important component of the mine-closure plans, which are required to ensure satisfactory mine site rehabilitation. Considerations of socioeconomic impact of mine closure and long-term responsibilities are presented.
