Coal gangue is the solid waste discharged in the process of coal mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation.

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 …

The typical method of assessing surface mining economics for a coal seam is a calculation of overburden (native rock and soil above a coal seam) moved per clean ton of coal produced, commonly referred to as "mining ratio". The higher the mining ratio (or more overburden moved per clean coal ton), the higher the cost of producing coal.
