Drill bit size — inches ↔ mm ↔ gauge number
Convert drill bit diameters between fractional/decimal inches, millimeters, and drill gauge number sizes.
Rock density ↔ tonnage — volume to weight for blasting
Determine solid rock and broken loose rock tonnage from volume based on rock type densities, useful for blasting and haulage design.
Explosive charge weight — rock volume ↔ kg of explosive
Estimate required explosives (kg, lbs) for blasting a rock volume using powder factor models for open-pit mining.
Drilling rate — ROP in m/hr ↔ ft/hr
Translate Rate of Penetration (ROP) and calculate specific drilling time, drilling speed efficiency, and shift performance.
Ore dilution — grade ↔ waste ↔ recovered grade
Calculate recovered ore grade, tonnage adjustments, dilution percentages, and mining waste contamination levels.
