The issues of optimization parameters of quarry transport systems

Authors: Zhuravlev A.G.

The cost of technological transport in open-pit mining for medium-depth quarries reaches 50 % of the total cost of production of commercial ore, and for deep-exceed this figure. Therefore, optimization of quarry transport systems is an important element in improving the efficiency of mining. The most important element of optimization is through her character the use of optimization to all linked processes on the basis of objective criteria of efficiency, unity and objectivity of the source data, using multilevel data from sensors mounted on the mining and transport machines to total economic values for processing. A promising direction for the implementation of tools for optimizing the processes of open pit mining and in particular transport systems of quarries, as one of the most important subsystems, is the end-to-end digitalization of mining production. The article presents the results of research and methodological approach to the creation of methods of optimization of complex transport systems on the basis of complex computer modeling, both simulation and economic and mathematical. The concept of TSC optimization methods in the absence of expressed maxima or minima of the parameters reflecting the optimization parameters is proposed. The possibilities of optimization of transport systems due to controlled transients are shown, it is established that the rational organization of the transition process provides cost savings of up to 2 times or more. The concept of a dynamic model of the quarry transport system development, reflecting the transition processes in its formation, is presented.

Keywords: quarry transport system, optimization, modeling, digitalization, technical and economic indicators, simulation.
