Open-Pit Stripping Ratio Calculator
Calculate volumetric (m³/m³) and mass (t/t) stripping ratios for open-pit mine planning.
💡 Engineering Knowledge PrimerOpen-pit stripping ratio compares waste overburden volume or tonnage moved per unit of economic ore extracted. Lower stripping ratios indicate higher open-pit mining profitability.
CALCULATION SCOPE — Deterministic calculation within the published assumptions. Independently verify all design decisions and project-specific code requirements.
