Abstract
At present, the use of standard technical and economic indicators of a mining enterprise to account for the operation and repair of BelAZ heavy-duty mining dump trucks does not provide a complete understanding of the reasons for the failure of these machines and all mining equipment. This makes it difficult to determine the initial causes of failures and the conditions for their occurrence, which in turn hinders the development of more effective maintenance and repair strategies for BelAZ dump trucks. To solve this problem, it is necessary to use formulas for calculating reliability indicators, such as the Stegers formula and the mathematical expectation of time to failure. To solve this problem, it is necessary to use formulas for calculating reliability indicators, such as the Stegers formula and the mathematical expectation of time to failure. These methods allow you to more accurately determine the likelihood of failures and identify the most likely causes of its occurrence. Thus, they contribute to a more effective management of the risks of equipment failure and increase the reliability of the system for the use of BelAZ heavy mining dump trucks and their repair. However, the use of formulas for calculating reliability indicators requires a higher qualification of employees of a mining enterprise, additional knowledge and skills in the field of mechanical engineering, mathematics and statistics. In general, the use of technical and economic indicators in combination with formulas for calculating reliability indicators is an important tool for improving the efficiency and reliability of the system for using BelAZ dump trucks and their repair at a mining enterprise. However, in order to achieve maximum efficiency of equipment operation, it is necessary to take into account all possible factors that affect the process of operation and repair of BelAZ heavy-duty mining dump trucks, as well as constantly improve risk management methods and tools.
