Planning for temporary or sudden closure
Temporary closure (p61) is a suspension of mining activities for a limited period. During temporary closure, the site is maintained. In sudden closure, a mine goes into final closure ahead of the previously planned timeline.
During temporary closure, maintenance works are carried out in anticipation of the site returning to active production. From a regulatory and closure planning point of view, many aspects of temporary closure should be indistinguishable from regular operations.
At each stage of the mine life, it is good practice to have a contingency closure plan in place for sudden closure that identifies the key areas of the site closure plan that will require modification in the event of a sudden closure.
For the largest risks, the critical control management (CCM) process provides a practical approach to providing control over large or potentially catastrophic events that are identified through the risk management approach.
