Belt conveyor is a common means of transport in underground mines. At the same time, longwalls equipped with belt conveyors face high fire risk. One of the fire causes on belt conveyors is the seizure of rollers and their friction on the loaded belt in the long flight regions. The modern detectors of fire on belt conveyors fail to ensure ultra early sensing of inflammation. This article describes modeling of heating of a faulty roller in friction with a moving conveyor belt with a layer of coal dust. The modeling has found the rate of heating of the belt conveyor roller up to the temperature of the ultra early fire development with inflammation of coal dust particles, and the degree of effect of the coal dust layer on the fire onset speed. The graphic chart is plotted for the heat balance of a belt conveyor roller in friction-induced heating.
