PA Mining History

Early room-and-pillar mines did not include retreat mining they relied on manual labor to cut the coal at the working face and the coal was hauled from the mine by horse and wagon Today many room-and-pillar mines use mechanized continuous mining machines to cut the coal and a network of conveyors that transports the coal from the working face to the surface continuous haulage...
