摘要

摘要: 针对煤矿井下电磁波能量可能存在瓦斯爆炸危险的问题，对电磁波传输过程中的电磁谐振原理、磁耦合谐振搭建等效电路，将金属结构引入天线传播理论模型进行分析，搭建谐振耦合系统进行电磁仿真验证。仿真结果表明：单环天线和单环接收线圈在谐振耦合的情况下，金属断点处能够产生较高的电势差，能量传输效率很高。电磁能仿真分析为射频电磁波防爆问题提出了解决路径，对射频电磁波防爆进行了电磁波方面的基础性分析探索。

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.
