Stripping ratio Wikipedia
In surface mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity It is a number or ratio that express how much waste is mined per unit of ore The units of a stripping ratio can vary between mine types For example, in coal mining the stripping ratio is commonly referred to as volume/weightThe 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 usedHowever, for hard rock mines where the geology is usually complex with the presence of various rock types, tonnage (t) is usually preferredStripping ratio and pit limit Basic Mining TechniquesA strip ratio, or stripping ratio, is an important measurement related to the openpit mining process It represents the amount of waste material, also known as overburden, that must be moved in Stripping Ratios: What are They and Why are They Important
