[0002] Tunnels are engineering structures buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel door. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] During the actual construction process, tunnels need to be excavated or blasted. During the excavation or blasting process, a lot of dust is often generated, which affects the construction line of sight and is inhaled by workers, affecting their health.
