VIBRATION AND CURRENT SIGNATURE MONITORING EXPERIENCES AT THE MÁRKUSHEGY MINE PLANT.

The paper presents the results obtained during the years of vibration and current signature monitoring at Márkushegy mining plant, before its final closure. The large amount of recorded data has been used for a statistical analysis, being useful for deriving conclusions regarding the incidence of different kind of faults occurred at main underground and surface equipment of an underground coal mine. The importance of inter-inspection time period on the capability of monitoring to increase up-times is revealed. The gained experience, which is disseminated in the paper could be a valuable guideline to design the condition-based maintenance of operating mines. [ABSTRACT FROM AUTHOR]
