National Park Service. A coal seam is a black banded or dark brown coal deposit evident in rock layers. These deposits are below the ground level and, based on their distance from the surface, can be extracted using techniques of either deep or strip mining. Such seams undergo natural formation of coal and function as a typical supply of coal.
