Description

Technical Field

[0002] Mine ventilation refers to the input 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 enough 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 underground climate 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 blocking airflow.
