Mining is an intensive type of land use with potential for environmental impact over a limited area. When closure occurs, it should address both environmental and safety aspects. Mine reclamation is an ongoing program designed to restore to an acceptable state the physical, chemical and biological quality or potential of air, land and water regimes disturbed by mining. The objective of mine reclamation is to prevent or minimize adverse long-term environmental impacts, and create a self-sustaining ecosystem as near as practicable to what existed before the mining activity.
