Real –time dispatching modelling for trucks with different capacities in open pit mines / Modelowanie w czasie rzeczywistym przewozów ciężarówek o różnej ładowności w kopalni odkrywkowej

Abstract: Application of fully automated systems for truck dispatching plays a major role in decreasing the transportation costs which often represent the majority of costs spent on open pit mining. Consequently, the application of a truck dispatching system has become fundamentally important in most of the world's open pit mines. Recent experiences indicate that by decreasing a truck's travelling time and the associated waiting time of its associated shovel then due to the application of a truck dispatching system the … Show more

“…As more than 50 percent of total mining cost is accounted for material handling systems (Ahangaran et al, 2012;Alarie & Gamache, 2002) optimizing the utilization of shovel fleet and truck fleet is a concern of mining companies. Thus, finding a fleet of trucks that optimizes the utilization of shovel fleet and truck fleet at the same time is vital.…”

“…For tracked vehicles with skid steering, this impact is presented in the form of overtaking caterpillars turning radius dependence on the so-called "resistance to motion factor", and in a turning resistance torque dependence on the turning radius of the machine [11]. However, for a heavy hauling and transport equipment, which are openpit trucks, the turning radius dependence on the friction coefficient is not presented in open sources.…”

“…1) and assume that the turning point of directive tire imprint coincides with its geometric center. Based on the known approaches of the tracked vehicles motion theory [11], an elementary contact force, which is acting on the wheeled mover on the side of the ground contacting area can be represented as the following Eq. (2), (N):…”

“…Several truck types with different capacities were considered for evaluation of their proposed model. Ahangaran et al (2012) presented integer programming to minimize the transportation costs in open pit mines. Their model considers the difference between the expenses of unloaded and loaded travels.…”
