A comparative analysis of the operational characteristics of the main components of BELAZ mining vehicles has been carried out. It is shown that the choice of type and means of career transport is determined by a number of factors and, first of all, by the characteristics of the transported cargo, the distance of transportation, the scale of work and the pace of their development. The power of vehicles depends on the scale of work (freight turnover), and the pace of mining operations determines the requirements for the operational reliability of career vehicles. The dependence of the dump truck failure parameter on the service life is disclosed. The analysis of the state of metal structures of structural elements of the dump truck BELAZ-7530 based on the method of non-destructive testing is given. As a result of the analysis of thermal imaging and measurements of the thickness of the walls of the motor housing, it was established that the amount of wear depends on the heating temperature of the metal structures.
