Strip Ratio The stripping ratio is the most influential economic factor in the evaluation and planning of open-pit coal mines. It represents the volume of rock both above and within (partings) coal seams expressed in Bank Cubic Metres (BCMs) which must be mined to obtain 1 tonne of raw or clean coal.
