Method and device for predicting, adjusting and controlling environment in tunnel

The invention provides a method for predicting, adjusting and controlling the environment in a tunnel. The method comprises the steps that a current environment quality value in the tunnel is determined according to quality parameters of a current environment in the tunnel; according to change data of the current construction scale in the tunnel, the environment quality change trend in the tunnelis estimated; and according to the current environment quality value, the environment quality change trend and a current working gear of a ventilating device in the tunnel, the ventilating strength ofthe ventilating device is controlled, and thus the environment quality value in the tunnel is restored into a preset high-quality environmental value range. According to the method, by determining the current environment quality value in the tunnel, combining the change data of the current construction scale in the tunnel and adjusting and controlling the ventilating device in advance according to the current working gear
