Investigations of the Phenomenon of Spontaneous Heating of Chloroprene Cover Wear-off in Fire-resistant Conveyor Belts

摘要

The paper presents investigations into the phenomenon of spontaneous heating of rubber wear-off from covers of fire-resistant chloroprene conveyor belts. The results of thermal analysis of cover fragments, and cover wear-off in an atmosphere of air and of nitrogen are reported. It has been found that the phenomenon of spontaneous heating of rubber wear-off from covers of fire-resistant chloroprene conveyor belts used in coal mines creates a hazard of fires.
