A tunnel collapse monitoring device for mining and a tunnel collapse warning method

The application discloses a tunnel collapse monitoring device and a tunnel collapse warning method, and relates to the technical field of mining. The collapse real-time monitoring device comprises a reference positioning device, a collapse warning triggering device and a feedback alarm device. The reference positioning device and the collapse warning triggering device are assembled with each other and are located above the outside of the mining tunnel. The feedback alarm device is located in the inside of the mining tunnel and corresponds to the location of the collapse warning triggering device. The application is used for monitoring the collapse of the tunnel when mining in the mountain with small slope and low height. According to the planned mining direction and length, the collapse real-time monitoring device is arranged above the mining tunnel in advance. The signs before the collapse are monitored by the collapse real-time monitoring device, and the warning signal is transmitted to the people in the mining tunnel in time. The warning feedback speed is fast, and the specific collapse position can be warned.
