Abstract
The feed switches in coal mine tunnels are opened and closed frequently, and by which electrical fast transient/burst is produced to interfere electromagnetic environment surrounding. The results can be concluded through analysis and test of electromagnetic radiation environment within the coal mine substation, the data of electromagnetic disturbance when equipment at starting moments are larger than those at normal operation, and the device power(voltage) is greater, the greater interference, the wider interference bandwidth.
