The paper discusses the advantages and shortcomings of resonance and single-frequency single-wire induction communication systems for mines. The issues of creating a magnetic induction communication system based on the twin transmission line (the MIKON-Tel queuing system) and the prospects for using small antennas to arrange two-way communication channels through the rock have been considered. The possibility of creating a multichannel queuing system for subscribers, which operates in a wide frequency band using a twin induction transmission line and small ferrite resonator antennas, is shown. The antenna designs used for magnetic induction communication in mines have been considered. High level of radio frequency signals has experimentally been proven when using a twin line and small antennas. The specific signal attenuation along the route in the coal mine was 4 dB/km. The results obtained prove the fundamental possibility of designing multichannel induction communication systems with a guaranteed communication range of over 4 km from the base station.
