Transport of Coal. Finally, the mined and processed coal must be transported. Transportation can be more expensive than mining the coal. Nearly 70% of coal delivered in the United States is transported, for at least part of its trip, by train (figure (PageIndex{e})). Coal can also be transported by barge, ship, or truck.

First of all, the layer of earth – overburden – above the first coal seam has to be removed. (The seam can be up to 200 meters below the surface.) All the earth around the base of the seam is removed before extraction begins. When the hole is large enough, the miners dig down to the next layer of coal.
