Abstract: Aiming at the problem that electromagnetic wave energy in underground coal mine may have the danger of gas explosion, the equivalent circuit of electromagnetic resonance principle and magnetic coupling resonance in the electromagnetic wave transmission process were established, the metal structure was introduced into the antenna propagation theoretical model for analysis, and the resonant coupling system was established for electromagnetic simulation verification. The simulation results show that when the single ring antenna and single ring receiving coil are resonant coupled, the metal breakpoint can produce a high potential difference and the energy transmission efficiency is very high. Electromagnetic energy simulation analysis for radio frequency electromagnetic wave explosion-proof problems proposed solutions, carried out the basic analysis and exploration of radio frequency electromagnetic wave explosion proof.
