Technical Field

[0001] The utility model belongs to the technical field of engineering monitoring devices, and in particular relates to a working face monitoring device used for tunnel construction using a drill and blast method. Background Art

[0002] When the drilling and blasting method is used to excavate a tunnel, blasting the working face is the main excavation process. During blasting, holes are first drilled in a small part of the working face and an appropriate amount of explosives are placed. A small notch is first blasted to provide more open surfaces for subsequent blasting. The notch is then expanded to the entire working face. The blasthole positions are arranged according to the drilling and blasting parameter diagram, and finally the explosives are detonated to realize the excavation of the working face. When the working face is blasted, construction workers need to retreat more than 200m from the blasting site to ensure personal safety. As the surrounding rock of the working face is exposed to a large area right after the blasting is completed, and the toxic and harmful gases or smoke generated by the blasting cannot be manually inspected and judged immediately after the blasting, it is necessary to use drones to monitor the situation inside the tunnel.

[0003] However, most existing drone monitoring devices are composed of only drones and cameras. The drones are directly exposed to the outside, and the dust content in the air after the explosion is relatively high. The dust adheres to the surface of the camera at will, affecting the shooting clarity and thus the monitoring effect. Utility Model Content
