Investigation of Excavator Performance Factors in an Open-Pit Mine Using Loading Cycle Time

摘要: This study presents the effect of excavator model, loading operation location, shift availability and truck-shovel combination on cycle time productivity an open-pit mine. The was used to assess material system performance which is one key components total for transportation in Loading among during being handled. data analyzed was collected from a computerized dispatch at GGM 62,000 dispatches per month involving several shifts, 14 excavators 49 trucks were loaded. About 4465 1276 truck assessed using each period four months (between August December). Under fixed tonnage loaded waste type (33 t non-acid forming rock), it observed that depends location Average times, PDFS and CDFS series identify differences under different situations. It concluded excavators, model combinations strongly affect process
