OPTIMAL SEQUENCING OF TASKS IN UNDERGROUND COPPER PRODUCTION AND DECISION RULES
In underground mining such as in the Chilean copper industry, in every working shift a fleet of LHD (load-hump-dump) vehicles must be allocated to a haulage network of streets for extracting ore from drifts according to a plan-driven strategy. This plan is hierarchically decided by a higher management level and it contains the number of ore bucketfuls to be extracted from each drift within a street in each working shift. In this paper, an integer programming (IP) model for minimizing the maximum completion time (makespan) of tasks within a street is formulated. Next, the model is reduced to a set of decision rules of simple application by the LHD operator in the working environment. The main benefit, besides improved performance, is that the derived decision rules are easy to compute and integrate into the decision making process.
