Abstract: This paper presents some research results in the development of an algorithm for creating a unified diagnostic criterion for diagnosing the most widespread defects in the power-mechanical equipment of mining shovels, such as misalignment of unit shafts, imbalance of rotating elements and violation of the rigidity of the support system. Analysis of experimental diagnostic data obtained on the operating equipment of ESH- and EKG-type mining shovels made it possible to classify the basic defects of this equipment. Also, the substantiation and formalization of diagnostic signs and rules in the field of vibration analysis, suitable for the development of a single diagnostic criterion, has been carried out. It is proved that the created criterion can be used as one of the elements of the basic platform for introducing the concept of servicing equipment based on its actual state. The scientific results obtained within the framework of this study prove the fundamental consistency of the proposed methodology for creating unified criteria and its effectiveness for assessing and predicting degradation processes on the equipment of mining machines. The implementation of the proposed approaches to improving the analysis of vibration parameters will optimize the logistics of mining enterprises and reduce the number of industrial accidents associated with the unacceptable state of the equipment being operated.
