Abstract
The invention relates to a method for detecting a communication failure of a mine leakage communication network. The method solves the defect that the existing simulation leakage communication network cannot monitor and manage trunk equipment and discharge faults accurately and quickly when faults occur. An analog modulation/demodulation circuit and a data processing unit are arranged in a repeater; commands sent by a demodulation network supervisor are received by a down link; the data processing unit is used for matching the received commands so as to judge whether the commands are sent to the equipment or not; if so, feedback response information is sent to the network supervisor by the up link modulation; and if not, no responses are generated.
