Abstract: Implementation of the system of maintenance of mining equipment according to its actual technical condition requires from mining enterprises not only creation of diagnostics service, equipped with modern technical means of nondestructive control and staffed by specialists on providing engineering reliability of the monitored equipment. Processing of large amount of information about technical condition of controlled objects requires use of special knowledge in the field of mechanical wear of contacting surfaces, theory of reliability of mechanical systems, statistical processing of results of passive experiments and methods of prediction of the product workability loss. All this requires creation of a universal prognostic model of mining equipment units and assemblies degradation, which takes into account a large amount of diverse information, including both external (mining-technical and weather-climatic operating conditions, qualification of mining machinery operators) and internal (operating mode, exploitation history) factors on mining machinery serviceability indicators. The main difference of the developed model from the existing ones is in the use of new unified diagnostic criteria as modeled parameters, each of which can replace a large number of diagnostic attributes and rules in the field of vibration control, which will allow to give up high requirements for vibrodiagnostic specialists.
