Safety analysis of electromagnetic wave energy received by underground columnar metal structuresChinese Full Text English Full Text (MT)

FAN Sihan;YANG Wei;TIAN Zijian;

Abstract: In the narrow space underground， it is necessary to install brackets， lighting lines， steel rails， coal trucks and air doors， resulting in the concentration of metal structures underground. Underground metal structures may receive electromagnetic wave energy from transmitting antennas through magnetic coupling or receiving radiated electromagnetic waves. If there are breakpoints in the metal structure， an induced voltage can be generated at the breakpoint. If there is scraping at the breakpoint ... More
