Knowra Land reclamation Land reclamation Land reclamation restores land disturbed by mining or other industrial activity, aiming to stabilize terrain and recover ecological or productive uses.
Mine spoil : Waste rock and overburden removed during mining and left in piles or dumps. Its stability, chemistry, and placement determine how reclaimed mine land performs.
Reclaimed mine land : Land restored after mining for ecological, agricultural, recreational, or other uses. It is the direct outcome of reclamation, with success judged against intended uses.
Ecological restoration : The practice of assisting the recovery of degraded, damaged, or destroyed ecosystems. Land reclamation often uses restoration goals, though industrial sites may require different endpoints.
Navajo Mine : A coal mine in New Mexico that supplied the Four Corners power plant and has undergone reclamation. Its reclaimed areas illustrate restoration in the arid landscapes of the American Southwest.
Topsoil : The uppermost soil layer, typically rich in organic matter, nutrients, and biological activity. Stored topsoil can restore growing conditions after mining reshapes a site.
Landfill closure : The engineering and long-term care of a landfill after it stops accepting waste. Capping, drainage, and revegetation overlap with industrial land restoration.
Land degradation : A persistent decline in the biological or economic productivity of land. Reclamation aims to reverse damage that can otherwise reduce land productivity.
Bauxite mining in Australia : The extraction of aluminum-rich bauxite from Australian deposits, including mines in forested regions. Rehabilitation in Western Australia has tested whether mined forests can recover their ecological structure.
Acid mine drainage : Acidic, metal-rich water produced when sulfide minerals in exposed mine materials react with air and water. Reclamation must prevent or manage this persistent source of water pollution.
Brownfield : A property whose reuse may be complicated by actual or suspected environmental contamination. Reclamation can prepare previously industrial land for safe reuse.
