Mining & Drilling Calculators
Translate drilling bit specifications across metrics, estimate blasted rock density tonnage parameters, calculate industrial explosive powder factor payloads, assess Rate of Penetration drilling performance, and chart geological ore grade dilution metrics.
Rock Tonnage & Volume
Determine solid rock and broken loose rock tonnage from volume based on rock type densities, useful for blasting and haulage design.
Rock Mass Profile
Engineering Core Report
Mine Ops & Blast TechSolid In-Situ Mass Tonnage
Blasted rock expands in volume because of the void space (interstitial air gap voids) created during fragmentation.
