Abstract: Nowadays and in the near foreseeable future the quarry road transport will be the most common in the open-cut mining method. This is due to a range of advantages of open-pit dump trucks usage as compared with other types of quarry transport, i.e. autonomy, the possibility of using in any mining engineering and climatic conditions etc. At the same time, this type of quarry transport is the most expensive and the questions related to operational cost reduction are relevant. The market of open-pit dump trucks in Russia features a large number of different producers. Many of them offer open-pit dump truck in almost all loading capacity classes. At the same time, open-pit dump trucks of different producers are characterized not only by the price but also by the design features, including overall dimensions. The mining enterprises could incur significantly greater quarry reconstruction costs to create the necessary transport communication with security conditions if they are guided by the initial cost of open-pit dump trucks and costs on their consequent service by selecting open-pit dump trucks in the same class of loading capacity. The actual problem of selecting the ground mining and conveyor equipment for open-pit mining is considered in the present paper. The dependencies of changing the volumes of recovered minded rock from the width of haulage berm for open-pit dump trucks from different classes of loading capacity were established. The application of the suggested approach and the developed Program of automated parameters calculation of quarry transport communications for different types of open-pit dump trucks will allow selecting the open-pit dump trucks during the quarries reconstruction with minimal volumes of through quarry of open pit side and costs over the planning period of the deposit development.
