PA Mining History

The room-and-pillar mining method is used in all of Pennsylvania's underground bituminous coal mines including longwall mining operations, where it is used to develop the haulage and ventilation systems, and to delineate and support the longwall panels Until the relatively recent advent of modern longwall mining, room-and-pillar mining had been the prime method for underground bituminous coal.

Basic Information about Surface Coal Mining in

"overburden" (rock above the coal seam), and "interburden" (rock between coal seams) Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all fit back into the mining pit, and disposal alternatives are limited The usual method of disposing of this excess.

Coal mining

Coal mining: Coal mining, extraction of coal deposits from the surface of Earth and from underground Coal is the most abundant fossil fuel on Earth Its predominant use has always been for producing heat energy It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th.

Longwall mining

The basic idea of longwall mining was developed in England in the late 17th century Miners would undercut the coal along the width of the coal face, removing coal as it fell, and using wooden props to control the fall of the roof behind the face this was known as the Shropshire method of mining.
