Description

technical field

[0001] The invention relates to the technical field of mine ventilation devices, in particular to a working face air regulating device for underground excavation. Background technique

[0002] Underground mining operations are mostly at a depth of 200m-1000m below the ground. In order to ensure the safety and normal work of underground workers, it is necessary to continuously deliver fresh air to the underground to ensure the normal breathing of the workers, and at the same time adjust the temperature and temperature of the underground environment. Humidity is used to ensure a good working environment for underground workers. While delivering fresh air, the underground ventilation network is used to discharge harmful gases generated during the operation of underground equipment from the underground roadway.

[0003] In the prior art, generally, corresponding ventilation ducts are set up under the mine to ventilate the air under the mine, and in the ventilatio...
