The article deals with the monitoring of the technical condition of the equipment of mine shaft lifting rigs that have been in operation for more than 50 years in rock movement zones. The analysis of the state of the profiles of the conductors of mine shafts with a long service life is performed. A solid model of barrel reinforcement and the results of calculations and distribution of stress concentration along the length of the shot are presented. The results of measuring the residual tiered wall thicknesses of the conductors and shots, as well as the residual values of the kinematic gaps in the track of the conductors between their working surfaces and the slip shoes of the vessel are presented. The results of measuring the dynamic parameters of the vessel-reinforcement systems under the conditions of active trunks are presented. The main provisions for the organization of a monitoring system for the equipment of mine shafts are developed.
