- Abstract
It is expected that mining machines work without unnecessary stops. In case of hoisting machine this requirement is critical. Thus, the damage detection is a crucial part in proper operation of transportation system. The hoisting machine transports the ore from underground mine. Even short breaks can influence the realization of the mine production plan. In this paper the vibration signal acquired on the hoisting machine operating in the underground mine is analyzed. The local fault generates the cyclic impulses. Intuitively, the cyclostationary methods can be applied which are capable of detecting the cyclic properties of the excitations related to the local damage. The results for the spectral coherence method are provided and analyzed.
