Abstract
In the current development, the object is the icing of drums of belt conveyors that work in open mines located at high altitudes and in winter conditions. A literature review was made of publications related to the problems at low temperatures and the presence of moisture, including the icing of rollers and drums of belt conveyors. Conceptual options are suggested to prevent freezing and related accidents. The options are accompanied by short methods for determining the main technical parameters. Finally, the advantages and disadvantages of the described options are indicated and, in conclusion, the best among them for the specific working conditions. A stationary or a mobile heater is chosen as a better option.
