[0002] Mine ventilation refers to the introduction of fresh air into the mine to increase the oxygen concentration in order to dilute and remove toxic, harmful gases and dust in the mine. The basic tasks of mine ventilation are: to supply sufficient fresh air underground to meet the needs of personnel for oxygen; to dilute harmful gases and dust underground to ensure safe production; to regulate the climate underground to create a good working environment. In order to make the underground airflow flow and distribute along the designated route, it is necessary to build structures to guide and control the airflow in certain tunnels, namely ventilation facilities, which are divided into facilities for guiding airflow and facilities for blocking airflow. New large-scale mine ventilation systems are mainly diagonal and partitioned, while the expanded and renovated production mines are mainly mixed;

[0003] The existing coal mine ventilation devices only provide a single ventilation and air supply function, while the actual coal mine working environment contains a large amount of coal mine dust. This coal mine dust is mixed in the air and will be directly absorbed by the workers without treatment, thereby affecting the health of the workers.

[0004] To this end, those skilled in the art have proposed a ventilation auxiliary tool to solve the problems raised by the background art.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content
