Safety device capable of early warning mine tunnel collapse

The invention discloses a safety device capable of early warning mine tunnel collapse. The device comprises a protective plate, wherein the protective plate is fixedly arranged between rock layers, five sensors are arranged in an annular array between the rock layers, and the sensors are capable of monitoring stresses between the rock layers. The safety device capable of early warning mine tunnelcollapse is simple in structure, and convenient to maintain and use; through a built-in sensing mechanism, the device is capable of monitoring the rock layers of a mine tunnel in real time, and when acollapse risk of the rock layers occurs, a corresponding warning device and a corresponding escape protection device are quickly started, so that the safety of the construction personnel is greatly guaranteed, the casualties of the personnel are reduced, and the personnel in the mine tunnel are assisted to rapidly evacuate a dangerous area; and moreover, the rescue personnel can quickly find thetrapped personnel for rescu
