ABSTRACT. Purpose. The state of open–pit mining, formed at Ukrainian enterprises, as well as the state of the mineral raw materials market require the search for new, more economically feasible approaches to open mining operations. Such a solution is the widespread use of cyclical–streaming technology. The aim of the paper is to research the interconnection between the main technological parameters of cyclical–streaming technology. Scientific novelty. In the paper relationships are established and the rational values of the parameters of the cyclical–streaming technology are determined, which
contributes to improving the economic indicators of deposit development. Practical significance. The mathematical modelling of the main parameters of the cyclical–streaming technology is fulfilled. The obtained results of studies of the main parameters of the cyclical–streaming technology can be used by project organisations and mining enterprises in the design. Research results. The comparison of optimal indicators of operation of the excavator–automobile complex and cyclical–streaming technology is performed, as a result
of which the economic expediency of the latter was confirmed. It has been established that increasing the carrying capacity of more than 136 tons at the current level of development of machinery and technology in iron ore open–pits in most cases is not appropriate. At the same time, the influence of the efficiency of the excavator unit on the performance of the cyclical–streaming technology in general was investigated. As a result, it was established that the best technical and economic indicators will be reached using the EKG–10 excavator. In this case, the geometric capacity of the dump truck body must correspond to the capacity of the bucket, and the load capacity is up to 130 tons. Thus, the study confirms the technological parameters of the cyclical–streaming technology that have been developed in the open–pits of the mining and processing plants of Kryvbas region.

Key words: the cyclical–streaming technology, excavator–automobile complex, equipment performance.
