2017-7-26 The units for stripping ratios can vary and usually depends on the geological properties of the deposit and the commodity mined. It can be expressed in tonnes (t), or cubic meters (m 3).Usually for coal, cubic meters (m 3) or tonnes (t) are used.However, for hard rock mines where the geology is usually complex with the presence of various rock types, tonnage (t) is usually preferred.
