Resumen

KAGOGO, T.S.. A critical evaluation of haul truck tyre performance and management system at Rössing Uranium Mine. J. S. Afr. Inst. Min. Metall. [online]. 2014, vol.114, n.4, pp.293-298. ISSN 2411-9717.

The factors affecting haul truck tyre performance and the effectiveness of the management system at Rössing Uranium Mine were investigated with the aim of increasing tyre performance in terms of running hours until failure. The main objectives were to identify the types of tyre failure, their causes and cost implications, and evaluate the effectiveness of the management system. A site severity survey, weight study, and TKPH studies were conducted to determine the pit conditions, and an analysis of failed tyres carried out. The results showed that tyre performance at the mine has declined from 2009 to date, and the increase in lost value amounted to R5.7 million in 2012 alone. The main cause of tyre failure is loose rocks in the pit. The present management system in the load and haul department is not effective enough due to operational constraints it is facing.

Palabras clave : tyre failure; cost implications; types of failure; causes of failure; management system; TKPH; haul roads.
