In the article, the efficiency indicators of excavators used in open-pit mining processes proposed by the author were compared, and the indicators of efficiency in the mine when excavators performing cyclic operations and dump trucks worked as a single excavator dump truck complex. This procedure significantly increases the probability of completing the daily plan. This transportation of rock mass due to the redistribution of dump trucks between mining and loading excavators cause the failure of one or more aggregates of mining and processing equipment. The reliability of excavator-dumper complexes is evaluated in three stages: initial data collection, i.e mathematical modeling of the operation of the excavatordumper complex and calculation of efficiency indicators based on the system. When solving the problems of optimizing the distribution between the excavators widely used in the mine and ensuring the maximum productivity of the excavator-dumper complex, the research processes about the reliability assessment of the mining and exploitation processes based on the probability of fulfilling the daily plan for the transportation of the rock mass are cited. The proposed method is implemented as part of a computer program and allows to automate the operational management of the process of transportation of rock and the mass of the mined area in the quarry with the help of a mobile application. Currently, in the Republic of Uzbekistan, mines can be used in any quarries operated by road transport, regardless of the type of mineral extracted. This mining method, loading scheme, capacity of the park of digging and loading mechanisms will consist of controlled dump trucks.
