Asbestos Risk & Coal Miners High Exposure Risk from Mining

Sep 10, 2020 Open-pit mining allows companies to extract coal without having to send workers down into the Earth’s surface. This form of mining removes large patches of land temporarily, giving workers access to coal. Unfortunately, coal extraction can also cause asbestos fibers to become airborne. A good example of this is mountaintop mining.

The Environmental Impact of Mining (Different Mining

Mar 04, 2020 Underground mining, where miners tunnel beneath the Earth’s surface to extract mineral deposits, is rarer than open-pit mining. In 2014, it made up about 5% of all American mining operations — and has less of an impact on the surface. However, this doesn’t mean that underground mining doesn’t have an effect on the environment.
