To this day, the remains of many old coal mining towns can be seen throughout Southern Appalachia. Although life in the coal mining towns was a step up for the more impoverished Appalachian families, most found it to be a meager existence. Miners were typically paid $3-$5 a day for a 12-hour work day.

Longwall mining involves the full extraction of coal from a section of the seam, or 'face' using mechanical shearers. The coal 'face' can vary in length from 100-350m. Self-advancing, hydraulically-powered supports temporarily hold up the roof while coal is extracted. When coal has been extracted from the area, the roof is allowed to ...
Coal mining is a major cause of methane emissions, accounting for around 10 percent of the US' methane emissions each year. 6. Coal is a non-renewable energy source. Although we use coal like it is available in limitless supply, this is far from the case.

Strip Mining. In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock, i.e., the 'overburden' is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out ...
