Abstract. Internal dumping technology is widespread in the deep iron ore open pits. In most cases, when deciding on its usage, mining situation is analyzed narrowly, excluding the complex influence of internal dumps on the open pit’s cargo flows system. The purpose of the research is improvement of the shovel-truck system efficiency using the internal temporary dumps. The analysis is based on the current operating conditions of shovel-truck systems in deep iron ore open pits, characteristics of the internal dumping technology, geological and mining conditions that determine its application scope. Preliminary methodology of open pit transport scheme analysis with the further technique of internal dumping justification is showed in the article. The feature of the method is its ability to define the rational application areas of the technological schemes with internal dumping, ring movement and passing loading of haul trucks. In the proposed version, it is done in a few steps. Initially, system of optimization models is applied to define the required number of transport to perform the mining plan and to test the existing haul truck fleet transportation possibilities. After it, creation of the optimally located internal dump is checked as an opportunity to reduce the insufficient transport work. Lastly, simulation model is built to check the efficiency of the shovel-truck system in the changed conditions. The use of the methodology will significantly improve the quality of engineering decisions about the internal dumping usage in the deep iron ore open pits.

Keywords: shovel-truck system, ring movement scheme, internal dumping, linear optimization, simulation.
