Guide to Mining Calculators

This hub spans the full open-pit and underground workflow — from designing a blast and reconciling drilled metres, through hauling and processing tonnes, to the grade, recovery and economics that decide whether a block is ore or waste. It suits drill-and-blast engineers, mine planners, grade-control geologists, dispatch and pit-technical crews, and quarry supervisors.

Blast design and charge loading

Start with pattern and bench geometry to fix hole count, area and volume, then use powder factor, specific charge and ANFO density to check whether your explosive load matches the rock; reach for decking, timing and Kuz-Ram when fragmentation or vibration is the concern.

Drilling performance and hole accuracy

Use the shift, utilisation and cost-per-metre tools to track rig productivity and drilling spend; switch to the deviation and toe-position tools when you need to know where an angled or dipping hole actually ends up versus design.

Fleet, haulage and plant productivity

Size and balance the loading-and-hauling circuit with cycle time, match factor and productivity tools, then use grade resistance, rolling resistance and speed-vs-grade to sanity-check haul-road performance and fuel; add availability, OEE and crusher/conveyor throughput to find the real bottleneck.

Grade, recovery and reconciliation

Convert assays and blend stockpiles with the ppm/grade tools, then use recovery, dilution and cut-off tools to move from in-situ grade to recovered metal; keep BCM/LCM/tonnes and swell/strip-ratio tools handy when reconciling surveyed volumes to mill tonnes.

Underground development and services

Plan decline geometry, stope volumes and advance rates for the mining side, then size the supporting services — ventilation airflow, dewatering sumps, shotcrete and cable-bolt patterns — that keep headings safe and open.

Decline Grade & Distance Calculator Stope Volume Calculator Development Advance Rate Calculator Pillar Stability Factor Calculator Airflow Volume Calculator Sump Capacity Calculator Shotcrete Volume Calculator Cable Bolt Pattern Calculator

Mine economics and planning

Use NSR, cut-off and cost-per-tonne/BCM tools to test whether material pays its way, then mine-life, life-of-mine progress and strip-ratio sensitivity to stress-test the longer plan against price and grade moves.
