Simulation and Modelling of Transport Processes for the Needs of Mineral Resources Delivery Support

This article is focused on the transport processes as a means of the mineral resources delivery support. Time for loading the wagons affects their length of stay at the loading track as well as the waiting charges that affect operational efficiency. The theoretical part of the article is a brief characterization of the process of loading – ways, forms and types of used unloading mechanisms. The second part of the article provides resources for the development of the algorithm, especially type of minerals, operational conditions and performance of unloading mechanisms. Then, there is an algorithm of unloading the mineral resources from railway wagons by cyclically working grab unloaders taking into account the transport of mineral resources to other places. At the end, there is a graphic and simulation model of unloading as well as the results obtained by modelling for various variants of unloading a mineral resource.
