Limiting state models for drive ends of belt conveyors

This study considers a systemic approach to the promotion of safety and efficiency of transport systems in coal mines. The ensemble of components of belt conveyors is intrinsically integrated in operation of an underground mine, while all these components have different reliability and rates of wear. The failure analysis of main components of belt conveyors in the mining industry is presented. The proposed approach represents the drive ends of belt conveyors as a complex engineering system. The typical layout schemes of the drive ends and the percent of failures in preassembled members of the drive ends are studied. The probable causes of failures of these members are analyzed. It is shown that 60% of all failures are the failures of the frequency converter, and the total annual dead time due to these failures reaches 362 h. The structure chart of a belt conveyor drive end is described, and the components advisable to be subjected to reliability control are identified. The most informative diagnostic indicators of the technical state of drive ends are determined. The valuation models of the limiting state of the main components in the drive ends of belt conveyors by a set of diagnostic indicators are developed. The chief indicators are the parameters of vibration, temperature, lubricant and electrical parameters of insulation of electric motors. Application of these models makes it possible to create a methodological framework for the control of reliability of complex transport systems in mines.
