How Coal Works | Union of Concerned Scientists

Longwall mining involves cutting long tunnels into a coal seam and removing the extracted coal by conveyor belt. As the miners and the machinery move along the seam, a hydraulic support system temporarily holds the rock ceiling in place. Today, both room and pillar and longwall mining are performed with very powerful mining machines, which rapidly cut coal from the face of coal seams.

About coal mining impacts | Greenpeace International

 · Mining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage, can persist for decades.
