<p>In the article is presented the relationship of the technical condition of the elements of bearing supports of mining equipment and spectral features based on the analysis of the high-frequency component of the vibrosignal, allowing to determine the type of defects and predict their development. The results of experimental studies of the vibration of the support nodes of mining equipment are presented. Studies have shown a striking gap between complexity and the high cost of operating equipment and the low technological level of its service. Such a gap is one of the main reasons for unscheduled equipment shutdowns, long downtime associated with the detection and elimination of the causes of failures, and high repair costs, and emergency situations. Vibration monitoring technology is presented, which uses regular measurements of vibration parameters, their frequency analysis and mathematical modeling of degradation processes in machines using software packages. For vibration monitoring of mining equipment, provides for control and diagnostic vibration measurements. Control measurements are designed to assess the technical condition of mining equipment as a whole, as well as its individual components. Diagnostic measurements are designed to identify defects, develop recommendations for their elimination and determine the timing of the output of equipment for repair according to the actual technical condition.</p>
