stripping ratio calculation in mining

Strip itself is easily understood in coal mining where you may have 20 metres of overburden before you expose a 2 metre coal seam. In this case, it is a simple to just divide the length of the overburden by the length of the coal seam (20/2 = 10:1 strip ratio) That is coal mining or strip mining at its core.
