Abstract

This paper analyzes the random mechanical failures that occurred with SH 400 rotary
excavators in the open (surface) coal mine in Oslomej, Kichevo, North Macedonia,
for the period January 2019-2021, especially in the transport system of the excavator,
referring to the data recorded by the dispatching services of the power plant. The
paper deals with the failure hours and frequency of failures occurring in some
subsystems of SH 400 rotary excavators and coal crushers, especially the conveyor
rubber belt – their carrier structure, conveyor rubber belt, rollers, and drums. The
contribution of this paper is to present the methodology for identifying potential
failures before they occur, by applying FMECA as a qualitative and quantitative
analysis for the coal system and calculation of the risk priority number (RPN).
