Minimising long-term mining damage
M 22

ining is a temporary activity, with mines operating from anywhere between a few years and a few
decades. Increasingly, however, what happens after a mine is closed, and the impact this has on the local community and environment, has an important influence on the competitiveness of the mining operation.
While many countries have good local standards in place, a global approach has been missing up until
now. Managing a reclamation activity is very complex; it begins long before any mining actually starts and does not stop for many years after the last ore or coal has been mined. New mining projects are in general strictly assessed and a reclamation plan is compulsory, but a common global standard on how to manage this is not available yet. In addition, almost every country has experienced problems of some kind with mines that are no longer operational, often relating to collapsing slime or tailings dams.
