Abstract: Features and transmission paths of electromagnetic interferences of coal mine underground were analyzed, which were in electrical transmission tunnel, traction network and electric locomotive tunnel and electromechanical chamber as well as areas around communication system. Electromagnetic interferences in above areas were tested. Through analyzing the tested data, electromagnetic environment in different areas was evaluated according to GB 9175-88 Hygienic standard for environmental electromagnetic waves. The evaluation results show that the tested environments all satisfy one level standard of environmental electromagnetic field.
