The Environmental Impact of Mining (Different Mining ...

May 27, 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.

Environmental Risks of Mining

Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
