  • What is the difference between strip and open pit mining ...

    Strip mining is basically digging a ditch, or trench, from point A to point B. You pile the soil on one side of the ditch and whatever does not have what you are looking for (spoil) on the other side. When the coal or ore has been removed, you fill the trench with the spoil and cover it with the soil. Open pit mining is just a hole in the ground.
