The relevance of the work is determined by the research topic, which consists in determining the main parameters of the implement linkage of an open-pit excavator - a fundamentally new design of the implement such as a front shovel protected by the RF patent. Based on the mathematical model of the transmission mechanism, which is formed during the excavation of rocks under the combined action of the main digging mechanisms and the mechanism connecting the main mechanisms with the bucket, the relationships between the energy-power parameters implemented on the cutting edge of the bucket and the standard parameters of the main mechanisms are established. A computer calculation program has been developed for the standard parameters of the main mechanisms during mining of the face by the excavator. Results: The developed simulation model of the excavation process will create an adaptive workflow management system and increase the efficiency of the mining excavator.
