Coal Seams: Things You’ve Always Wanted to Know ...

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.

Most coal occurs in large deposits called coal beds and they are made up of bands or seams separated by layers of clay, rocks and other mineral substance. The seams of the coal vary in thickness from a fraction of an inch to several hundred feet. Coal lies at various depth in the earth and some is found just below the surface of the ground.
