Abstract
Problem Statement (Relevance). The economic development of the Russian Federation is largely determined by resource availability. Explored reserves of copper, iron ore, nickel and other solid minerals are significant and sufficient to cover domestic needs. Extraction of these minerals is mainly profitable by open-pit mining using a fleet of quarry mining equipment and transport. Quarry crawler excavators occupy a decisive place in the technological chain of extraction. The efficiency of excavator operation is determined and ensured in the conditions of modern production by the correct organization and implementation of a set of works on technical maintenance and repair, reduction of the number of failures and duration of downtime. Methods Applied. When solving the tasks, an integrated approach was used, including: system scientific analysis and generalization of previously published studies. The finite element meth-od was used to assess the stress-strain state of the elements of load-bearing metal structures of quarry excavators. Originality. The complex use of strain-gauging of the stress-strain state of structures and modeling of the loading process for different parameters of the face and the collapse of the rock mass in experimental studies made it possible to obtain the necessary amount of data for recommendations on improving the units of metal structures of excavators, the technology of their restoration and repair, as well as systematization of the rules and requirements for the operation of quarry excavators in severe mining and geological conditions. Practical Relevance. Development of recommendations for optimal control of a quarry excavator, which will ultimately reduce the number of failures of working equipment and increase its service life.
