Abstract: This article discusses the principles for implementing the methodology for using single diagnostic criteria for assessing the actual state of complex mechanical systems based on the generated vibration parameters, suitable for creating a test procedure for samples of mining equipment. The efficiency of applying the results of a complex diagnostic approach for assessing the state of mining equipment is substantiated. Only with the use of modern methods of vibration diagnostics it is possible to detect defects in equipment in a timely manner, regardless of their type and degree of danger. A concrete combination of the methods of nondestructive testing necessary for the implementation of complex diagnostic control is substantiated. The effectiveness of the developed complex of more than 120 diagnostic rules suitable for performing automated analysis of the parameters of the vibro-acoustic signal and detection of equipment defects on the basis of selective groups of informative frequencies is substantiated. It is shown that the developed united diagnostic criteria for assessing the technical state can be used to improve the methodology for standardization of parameters of mechanical vibration and for implementation of short-term adaptive forecasting of the degradation of the technical condition of mining equipment. The results of the research categorically proved the need for the transition of repair and maintenance departments of industrial enterprises to the system of maintenance of machinery based on its actual technical condition, a platform for the implementation of basic elements of which can serve as a developed set of diagnostic rules for the detection of defects. The principal validity of the developed methodology for testing equipment of mining machines is substantiated, the implementation of the basic principles of which will increase the reliability of mining equipment and minimize emergency failures of complex mechanical systems.
