Question 1. For this pit depth, which ramp grade gives the lowest cost per tonne? A gentle ramp is long (more road, more rolling-resistance work); a steep one pushes the motors to their limit. The sweep runs the full truck model on every grade from 4 to 16 % and compares it with a closed-form ramp model.
Question 2. How many trucks does one shovel need? The sweep simulates 6 hours of the whole fleet for 1 to 14 trucks and compares with queueing theory.
