Mine monitoring system

The invention relates to the technical field of monitoring, and discloses a mine monitoring system. The mine monitoring system comprises an underground monitoring module, a ground centralized controlmodule, an underground mutual access module and a ground and underground interconnection module, wherein the underground monitoring module comprises an information acquisition unit, a display interface unit, a communication interface unit and an alarm unit; the ground centralized control module is used for executing a remote setting function, remotely setting action parameters of a protection device and switching protection equipment when a dispatcher permits; and the underground mutual access module is used for communication between underground communication modules. According to the mine monitoring system, real-time on-line monitoring of an underground substation is realized, and a fault point can be quickly positioned when a fault occurs, so that a worker can effectively eliminate a fault and shorten a power fa
