Имитационное моделирование работы экскаваторно-автомобильного комплекса карьера

Abstract

The specificity of mining enterprises is the constant change in the transport network, which is associated with the development of mining operations, both in terms of and in depth. Career roads have stationary and temporary sections. Stationary sections are determined by the general scheme of the open pit, while temporary sites depend on the location of the open pit, dumps, warehouses, transfer points and other infrastructure facilities. An increase in the efficiency of mining operations is provided as a result of optimizing the type, number of rolling stock and transport work in the conditions of constant changes in the roads in the open pit. The paper proposes a simulation model that allows solving such problems. The model was created on the AnyLogic platform. A diagram of the process of modeling the operation of an excavator-and-dump truck complex is presented. In the modeling process, the principles of consistency, universality, and scalability are applied. An agent-based approach was used, which implies modeling each dump truck and excavator as a separate, independent object of the model. The simulation model presented in the article makes it possible to determine the optimal temporary road scheme for the movement of dump trucks. The article describes an experiment on choosing the location of a temporary section of the road to ensure optimal operation of the excavator-and-dump truck complex. The experiment considers subsequent changes in the road network, as well as the cost of its construction. As a model example, an excavator-and-dump truck complex consisting of six excavators was taken, with rock unloading at one site. The developed model was used to determine the performance indicators of the excavator-and-dump truck complex at a model mineral deposit.
