Abstract

The actual number of mining dump trucks required to work with a single excavator is usually obtained by rounding the calculated value based on truck availability or operational experience, sometimes adding a smaller-capacity truck. This paper presents an option to equip the haul fleet with an increased number of trucks to reduce downtime of the primary excavating machine.

Keywords

Excavator productivity, dump truck productivity, hydraulic excavator, excavator–truck complex, open-pit mining.
