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/weight. Whereas in metal mining, stripping ratio is unitless and is expressed as weight/weight. A stripping ratio can be expressed as a ratio or as a number.

Apr 04, 2016 The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR).This represents the highest possible units of waste that can be handled. If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining.
