Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
The once abandoned and now restored hard coal mine is a cool 53 degrees year round, and provides you the opportunity to see a day-in-the-life of the area's workers that powered the Industrial Revolution.

Sulfide oxidation is a common phenomenon associated with many mined ore bodies and extracted or processed waste. Where the products of these chemical reactions can enter a water body the result is often a reduction in water quality through the increase of acidity, metals and dissolved salts. Due to an attributed lower environmental impact the release …

In the mine context, pyrite and pyrrhotite are important iron sulfide precursors to the formation of thiosalts, including S 2 O 3 2−, in tailings storage facilities (TSF). The S 2 O 3 2− is often selected as representative because it is the dominant thiosalt present in mine water ( Miranda-Trevino et al., 2013, Range and Hawboldt, …
