Pollution from Mining

Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfurcontaining materials in the presence of water leads to highly acidic solutions. Toxic substances are brought to the surface ...

Environmental and other effects of mining and transport

Historically coal mining is associated with damage to natural landscapes and the rise and fall of the mining communities which grow up around mine sites. But the sector has grown and most mining companies now act with forward planning and responsibility to minimise potential negative effects on mining land and, in some cases, to leave behind a positive legacy. This study addresses the ...

Environment

The coal mining industry has a duty to ensure that water is fairly and appropriately distributed among stakeholders and mining operations. Mining companies tend to use potable water only for nonmining activities, such as staff accommodation and offices. Nonpotable water, otherwise known as industrial water, is used in mining and processing operations as far as possible.

Coal and the environment

· Effects of coal mining. Surface mines (sometimes called strip mines) were the source of about 62% of the coal mined in the United States in 2019. These mining operations remove the soil and rock above coal deposits, or seams. The largest surface mines in the United States are in Wyoming's Powder River Basin, where coal deposits are close to the surface and are up to 70 feet thick. .
