Calculation of the service life and assessment of the reliability of conveyor rollers under the conditions of the angren coal mine

The paper posed and solved the problem of determining the average service life of the belt conveyor rollers, which are used in the development of the conditions of overburden benches in the Angren open pit. The tasks of this work are considered to be the determination of the service life of the conveyor rollers by studying the static and dynamic loads of individual pieces of overburden of the cut. As a result of the research, a graph of the dependence of the service life of the conveyor rollers on the belt speed was obtained. Recommendations for the long service life of the belt conveyor rollers are presented.
