The substantiation of the theoretical and methodological approach was carried out as a result of identifying probabilistic indicators that affect the planned performance of the rolling stock and determine the properties of the types of activities for the maintenance and repair of rolling stock, the transportation of goods by transport units that provide the main production of oil and gas in Eastern Siberia. The work of special equipment is taken into account. The specificity of road, transport, climatic, seasonal conditions is taken into account when planning the production and labor intensity of each unit of rolling stock, presented as a set of parts, and assemblies.

“…Trucks typically contribute over 50% of the total haulage cost, and likes all other mining equipment, need to be preserved under an efficient maintenance program. 2 Any failure of each truck's sub-systems leads to failing the truck and accordingly stop the hauling operation. A dump truck is comprised of different sub-systems including engine, transmission, hydraulic, electrical, body, and tire.…”

Reliability analysis has a very important role in supporting the operation of a system in harsh working conditions such as mines. Haul trucks are considering as a main asset of an open pit mine. Dump trucks are comprised of different sub-systems and among them, tires have a significant effect on the haulage economy. This study focused on the remaining life estimation of the mining truck tires considering the environmental operating conditions at an open pit iron ore mine in Iran. To achieve this, the proportional hazard model was used to estimate the conditional reliability functions and then the mean residual life of tires at the various initial survival times. The results of this study show that the ambient temperature has a significant effect on the reliability performance. By increasing the initial life of tires from 500 to 1000 h, the mean residual life will be decreased by 21% and 30% in low (below 15°C) and high (above 15°C) ambient temperature levels. These results are helpful to keep the truck tire performance at a desirable level by considering the appropriate preventive maintenance intervals.

“…Обзор научно-технической литературы [1][2][3][4][5][6][7][8][9], посвященной исследованию транспортных систем на горнодобывающих предприятиях, показывает, что грузоперевозки обеспечиваются преимущественно пневмоколесным транспортом, где удельный вес карьерного автотранспорта приблизился к 75%. Определенно можно констатировать факт того, что колесный автотранспорт останется доминирующим видом транспорта на горных разработках еще в течение 20-30 лет вследствие отсутствия альтернативы с такими же функциональными возможностями.…”

“…Принимая во внимание, что на предприятиях Северо-Востока России парк транспортных машин представлен автосамосвалами модели Бе-лАЗ-7540, а также учитывая результаты обзора предыдущих исследований [6][7][8][9][10][11][12][13][14], необходимо обратить внимание на то, что аспектам эксплуатации и изучению надежности данного карьерного автосамосвала исследователями не уделено достаточного внимания, не говоря об особенностях эксплуатации на россыпных месторождениях. Таким образом, установлено, что существует научно-практическая задача, требующая решения.…”
