Abstract

The actual or operational number of quarry dump trucks required to work with a single unit of excavation and loading equipment is usually determined by rounding the calculated value depending on the availability of dump trucks or existing experience in operating excavator-truck complexes by adding a dump truck with a lower load capacity to the transport chain. This paper presents a possible option for equipping the transport chain with an increased number of dump trucks to reduce the downtime of the main excavator.

Keywords

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