An analysis of full truck versus full bucket strategies in open pit mining loading and hauling operations

ABSTRACT

This work analyzes two loading methodologies used in open pit: full truck and full bucket. The effect on production, fleet size and associated operating costs was simulated. The results indicate that when there is a shortfall in hauling fleet, the recommendation is full truck methodology. This recommendation, results in a lower fleet operating cost in addition to higher production than full bucket. However, for a surplus hauling fleet scenario, an exhaustive study is necessary. When the ideal coupling between equipment is exceeded, there is an acceptable range of waiting trucks before considering a change of methodology.
