Facilities | Aspects to be taken into account |
Underground mines | Backfilling of pits, slopes and ventilation shafts; effects of contaminated water from backfill, drainage of overburden |
Open-pit mines | Slope stability; groundwater and surface water management; security and access prohibition; drainage effects towards wells; removal of disposal roads. |
Treatment facilities | Removal of buildings and foundations; removal of fixed and mobile infrastructure; cleanup of facilities, fuel and reagent storage areas; waste disposal; site reprofiling and revegetation. |
Waste rock and the topsoil piles | Reinforcement of embankments; leaching effects on runoff; dust; visual impact. |
Management of the decantation ponds | Dam stability; geochemical changes in mine wastes; percolation effects through dams and bottoms of ponds; surface water and effluent management; dust generation from perimeters; access and security. |
Hydraulic facilities | Stability of dams, reservoirs, decantation basins, pipes, channels, outlets; sludge disposal from treatment plants; surface drainage and elimination of drainage effluent. |
Terrils | Containment of hazardous waste; dismantling of wastewater treatment plants; prevention of groundwater pollution; prevention of improper waste disposal |
Facilities | Removal of electrical and water supply facilities; remodeling of access roads and evacuation; reuse of supply yards and loading docks. |
Exploration areas | Rehabilitation of drilling areas and access roads. |
