Abstract:

In order to improve the transportation efficiency of open-pit trucks and reduce mining costs for mine enterprises, minimizing the comprehensive cost of open-pit truck transportation scheduling was set as the objective function, and constraints such as ore production, grade balance, and transportation time were considered. The SA method and the CSA were combined, and the SA-CSA algorithm was employed to optimize the scheduling of open-pit trucks. A large-scale open-pit mine was studied, and the optimization results of the SA-CSA with those of the SA algorithm and CSA were compared. The results indicate that the SA-CSA exhibits superior solution accuracy and convergence speed compared with the SA algorithm and CSA.

Key words: simulated annealing (SA) method, crow search algorithm (CSA), SA-CSA, open-pit mine, truck scheduling optimization
