In a typical open cast mining operation, investigation of how existing
truck performance compares with the highest achievable truck
performance is largely neglected. This paper addresses this issue by
proposing a computerised system that will provide a systematic method
for comparing existing truck operational performance to the highest
performance considered achievable. Through analyses of existing versus
achievable performances, various inefficiencies associated with truck
operations can be identified. These inefficiencies could occur due to
machine configurations, haul route design and conditions or operator skill
level. Remedial action should then be taken in a timely fashion to better
manage these factors and to ensure the fleet is always operating at its
peak efficiency.
