stripping ratio calculation in mining

In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore.For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock. Stripping ratios are typically reduced to show the volume of waste removal required to extract one unitStrip mining | Britannica,Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral..
