FIELD: mining.
SUBSTANCE: group of inventions relates to a tunnel communication method and a tunnel communication system. Tunnel communication support method is characterized by the fact that at least two receiving-transmitting devices are placed in the tunnel. One of them is placed at a distance not exceeding 1,000 m from the entrance to the tunnel, and is connected to the ground network. Another receiving-transmitting device is placed in the communication zone. Receiving-transmitting devices are connected to each other through a power cable with length not exceeding 700 m, the voltage of which is in range of 350...1,200 V.
EFFECT: creation of a method for communication support of a tunnel and a tunnel communication system with increased manufacturability.
