Stockpile Volume & Tonnage Calculator

Calculate volume and ore tonnage of conical and kidney/elongated stockpiles based on angle of repose.

💡 Engineering Knowledge PrimerStockpile tonnage estimation uses geometric volume modeling based on material angle of repose and bulk density. Accurate stockpile inventory calculations prevent mill feed starvation during mining delays.
OPERATING LIMITS — Geometric storage estimate only; distinguish usable/live capacity and verify geometry.

Technical Methodology & Engineering Principles

GOVERNING EQUATION
Base Radius R = H / tan(θ) Conical Vol = (1/3) × π × R² × H Elongated Vol = Conical Vol + R × H × Crest Length
Assumptions & Scope

Free-draining uncompacted cone/kidney geometry.

Operating Range & Boundary

Use finite, physically meaningful inputs within the stated operating assumptions.
