Coal Seam
A coal seam is a layer of coal found underground between other rock layers. Think of it like a layer in a sandwich, where the coal is the filling between layers of rock. When people in mining talk about coal seams, they're referring to these natural deposits of coal that can be mined. The thickness and depth of coal seams are important factors that mining companies consider when planning their operations. Some coal seams might be just a few inches thick, while others can be many feet thick, which affects how they're mined and what equipment is needed.
