Coal Mining 101 – The Coal Seam

UNDERGROUND MINING. A continuous miner in operation underground. Underground mining techniques, which account for the majority of West Virginia’s coal production, utilize machinery to drive tunnels under the surface of the land. These tunnels are situated in coal seams so as the machinery advances further underground, coal is removed.

Coal seam - Energy Education

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 ...

Equipment - underground COAL

Machine position or attitude is usually measured relative to other parts of the machine itself, to other equipment or the position in space. In fact what is usually required is the position relative to the coal seam as that is what has to be followed (though in some instances even this is not desirable eg sudden changes cannot be followed)
