穿透岩层地下电流场通信信道分析

Channel analysis on underground mine communication by electrical field through stratum

摘要: 考虑到传统的有线及无线地下通信方式的弱点,提出了利用电流场实现穿透地层的地下通信方式,并根据甚低频电磁波在地层中的传播特点,提出了利用恒流场模型作为电流场通信的电磁波传播模型,同时对电流场地下通信方式的性能进行了分析,并得到一些重要结论。

Abstract: On account of the weakness of conventional wire or wireless mine communication, a new method of underground radio communication through stratum by using electrical current field is proposed, In terms of the diffuse characteristic of VLF electromagnetic wave, the constant current field model is brought forward for the electrical current field communication, at the same time the performance analysis and some significant results are given.
