Abstract:
Purpose. To determine the rational parameters of reloading points for cyclic-and-continuous technology at open mining operations using dump trucks.
Methodology. The basis of the developed methodology was the modeling of the physical essence of the process of road transportation, which most fully corresponds to the simplest flow in the theory of mass servicing of the Poisson type, and the reloading point from the point of view of bunkering and storage can be considered as an open queuing system in which the waiting time for unloading is approximated by an indicative distribution.
Findings. As a result of the calculations, the rational capacity of the bunker and the rational number of unloading points were determined on the basis of the condition of uninterrupted unloading of dump trucks at the transfer point.
Originality. For the first time, a quantitative assessment of the technological parameters of the reloading points was done, taking into account the journey duration of the dump truck in the cargo and empty ways, the load capacity of the dump truck, the loading time, the total number of dump trucks required for servicing the excavators, and a number of other parameters. Thus, complex analysis of the operation of the quarry transport system was carried out.
Practical value. Based on the proposed methodology, the possibility of increasing the efficiency of the transport system in open mining can be planned in advance, which ultimately will improve the overall productivity of the quarry.
