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.
