A coal seam is a dark brown or black banded deposit of coal that is visible within layers of rock. These seams are located underground and can be mined using either deep mining or strip mining techniques depending on their proximity to the surface. These seams undergo normal coal formation and serve as a conventional coal resource.The reserves of coal are immense, and are the largest of all of
