FillFactorRatio is a handy planning tool for mines and warehouses. It helps you see how much stock you can count in a set time, based on shift hours and pace. Plan air flow underground and set regulators so each area gets the right fresh air. Tune blast layouts with clear links between stemming, burden, spacing, and hole size. Check truck roads for rolling drag and grade so climbs and drops stay safe. Estimate bucket fill and cycle time to match shovels and trucks better. Set pump duty and slurry solids for steady tailings lines, and confirm dragline reach and dump fit. Size refuge rooms, screen blast PPV, and check belt tracking to cut risk and keep work smooth.
