Machines used in opencast mines like bucket wheel excavators (BWE), spreaders and
others are extremely loaded structures. Interactions between bucket wheel and overburden …

The paper presents two model approaches to life cycle assessment of auxiliary mining
machines: one of them is based on reliability theory and the other on the principle of cost …

The issues connected with the prediction of mining machinery life are discussed. The basic
index of reliability is an average life. The formulas are substantiated for calculating the …

Tangential digging force is one of the basic descriptive parameters of bucket wheel
excavators (BWE). Knowledge of factors that influence its value is necessary for correct …

The authors analyze stresses and strains in elements of undercarriage steel constructions of
heavy haulers and state the law of mathematical expectation of stress amplitude. The …

Consumable supplies in mines (explosives and explosive devices, oil, lubricants, rubber,
protective devices, spare parts for machinery and equipment, flotation reagents, etc.) should …

In case of bucket wheel excavators (BWE) the digging forces are dominant sources of
vibrations. The influence of digging forces on steel structures of upper part of BWE depends …

Представлены два модельных подхода к оценке жизненного цикла вспомогательных
горных машин, один из которых основывается на теории надежности, а другой—на …
