The article describes the theoretical and experimental studies into the rolling resistance coefficient of rollers of belt conveyors in mines. The experimental testing based on the theory of similarity and dimensions has produced the relationships of the rolling resistance coefficient, the main structural parameters of bearings and the service properties of plastic lubricants at dynamically varied temperature and different belt speeds and roller loads. The reduction in the rolling resistance force applied to the rollers at the adjusted rolling resistance coefficient makes it possible to increase the operating energy efficiency of belt conveyors in mines due to the rational use of modern plastic lubricants.
