About one of the factors determining the failure rate in the working equipment of mining excavators

To date, the development of mining is carried out mainly opencast, which provides competitive economic indicators for the mining industry. Open mining of mineral deposits is characterized by an increase in the volume of processed rock mass and overburden ratios, production processes are improved due to advanced technologies, which entails the use of mining equipment of large unit capacity. So the efficiency of such equipment is ensured by its correct operation, minimizing the cost of its maintenance and repairs. The object of the paper is to establish and evaluate the factor that most significantly determines the failure rate in the working equipment of mining excavators.
