Learn More: Surface Mining vs. Underground Mining – Lakes .

Underground mines are large tunnels dug deep into the ground to extract minerals that are too far from the surface to be reached by surface mines—from veins that are more vertical. Miners quickly discovered that most of the iron deposits in the Adirondack region were at very steep, vertical angles.
