Chocks Introduction underground COAL

Roof support in early longwalls (in the days of hand mining) was by timber props and bars, withdrawn from the goaf side as the faces advanced and re-used if still intact. The horizontal cylinder in these chocks attached the chock base to the face coal haulage system (an AFC see later notes). so the greater the cost. The ideal

Coal prices and outlook U.S. Energy Information

2020-10-9  In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia. The higher cost of coal from underground mines reflects the more difficult mining conditions and the need for more miners.

Underground Coal Gasification netl.doe.gov

2021-5-30  Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the surface.1 Obviously
