Fast, client-side mining engineering calculators for open-pit load-and-haul operations. Zero setup, runs completely in your browser.
Compute single pass cycle durations (dig, swing, dump, return), tonnes per pass, required passes per truck, and instantaneous vs effective dig rate (t/h).
Determine whether your circuit is shovel-limited or truck-constrained. Calculates queue times, shovel wait percentages, and optimal truck fleet sizing.
