After mining finishes, the mine area must undergo rehabilitation to minimize environmental damage. This step in the mining process is critical to ensuring the sustainability of the land for future use. First, waste dumps are contoured to flatten them out and stabilize them. If the ore contains sulfides, it is covered with a layer of clay to ...

Mine-site rehabilitation is critical to mining as it underpins the social licence for mines to operate. Mining is often viewed in a negative light by the public rather than as an essential source of materials that does not harm people, places and nature. To change this perception, real improvements in mining practices and rehabilitation are needed.

The primary question when facing the recovery of a mine site should be what is the desired land use and ecosystem functions that have to be re-established again after mining. Those final land use targets are indeed quite broad (Pearman, 2009) and range from more direct human focussed outcomes (e.g. parks, food or timber production) to …

Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam-driven pumps could be used to remove water from the deep mines of the day. Early lighting systems were of the open-flame type, consisting of candles or oil-wick lamps. In the latter type, coal oil, …

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
