Surface mining is when miners take dirt away from the surface of the earth but they can only do this if the source is relatively near the surface. But there is a new study that companies are doing about this it's called surface strip mining, that's where miners dig up a long surface of the earth to get the resource and when they've got as much as they can get and then put back all the dirt they had taken so it can be replanted.
