Modelagem e otimização da operação de veículos na mineração de cobre subterrânea

Abstract: ResumoNa mineração subterrânea, diariamente, uma frota de veículo LHD (load-hauldump) deve ser alocada à rede de galerias para extrair o minério segundo um plano estratégico de trabalho. Esse plano é definido pela alta gerência e contém o número de cargas a serem extraídas desde os pontos de remoção de uma dada galeria para cada turno de trabalho. Nesse trabalho, formula-se um modelo de programação inteira (PI), para minimizar o makespan de uma galeria de trabalho, e propõe-se um algoritmo ótimo em tempo polin… Show more

“…The results showed that the best approach is to start from the drawpoints that have a greater amount of materials. Vasquez et al (2011) presented a job scheduling model to minimize the makespan using the integer programming (IP) mathematical optimization model. The models by Vasquez et al showed that the load-haul-dump (LHD) driver approach was close to their model solution.…”

“…Various types of fleet management systems (FMSs) have been developed at mining sites for the efficient operation and management of mining equipment [1][2][3][4]. The key technologies that are provided by FMSs in relation to loading and haul operations at mining sites include dispatching technology [1,[5][6][7][8][9][10][11][12][13][14][15][16][17][18] that identifies optimal combinations of equipment and adjusts dispatch intervals, routing technology [19][20][21][22] that identifies optimal equipment travel routes, and tracking technology [23] that monitors the current location and operational status of each piece of equipment.…”
