Abstract
Abstract: Previous computer programs simulating materials handling in open pit mines use a well-established model for the description of vehicle motion [2,3,4]. This deterministic model, assuming a constant acceleration, relies on a characterestic performance curve which relates vehicle speed with the propelling force (Rim pull) available at the drive wheels. The characteristic curves are supplied by truck manufacturers. The model assumes that a truck driver will always use the maximum power available at a given speed following the characteristic curve. However, this last assumption is not necessarily realistic. Moreover, not all manufacturers supply characteristic curves for their vehicles. On the other hand, the model which is constructed for big computers needs a very long time of execution when it is adapted in micro-computers. There is thus a need for a new algorithm for the calculation of truck travel-time, which is not dependent on characteristic curves, and which takes into consideration the real power available to the truck. This new algorithm is essentially to be applied on a micro-computer (Apple II 48 K). A program, called CALCUL, is described in this paper. This program is compiled by the package TASC to reduce the time of execution.
