Stripping ratio
Equations. The equations for stripping ratio are, for coal: ()for metal: ()where volume is typically expressed as m 3 or yd and weight is typically expressed as tonne or ton.. Use. It is common for the stripping ratio to be used as an indior of economic value for an open pit mine. This is because removal of waste is a cost to the mine whereas mining ore leads to revenue.
