The result is that metal mining activities are expanding and more and more of the world's metal stocks are above ground in use rather than below ground as unused reserves. An example is the in-use stock of copper. Between 1932 and 1999, copper in use in the USA rose from 73 kilograms (161 lb) to 238 kilograms (525 lb) per person.

Environmental Risks of Mining

When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul & Campbell, 2011).

The Pinal creek drainage basin in Arizona is a good example of the principal non-coal source of mining-related acid drainage in the U.S.A., namely copper mining. Infiltration of drainage waters from mining and ore refining has created an acid groundwater plume that has reacted with calcite during passage through the alluvium, thereby becoming less acid.

coal - Problems associated with the use of coal | Britannica

coal - coal - Problems associated with the use of coal: Coal is abundant and inexpensive. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous.

Mining is bad for health: a voyage of discovery | SpringerLink

Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners. I look at mining and health from various personal perspectives: that of the ordinary man ...

Environmental effects of mining - Wikipedia

Long-term storage of tailings and dust can lead to additional problems, as they can be easily blown off site by wind, as occurred at Skouriotissa, an abandoned copper mine in Cyprus. Environmental changes such as global warming and increased mining activity may increase the content of heavy metals in the stream sediments.

Pollution From Mining - TheWorldCounts

Fuelled by rainfall, there is a non-stop flow of water contaminated with acid and heavy metals from the mine. And no solution in sight to stop the pollution. A common problem. Acid that drains from mines is a very common problem in mining. It is also one of mining's most severe and important environmental challenges.

Mining | Environmental Issues

Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. This causes serious damage to buildings. It lowers the water table, changing the flow of ...
