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.
