When excavating tunnels, in order to supply personnel with fresh air, dilute the gas in the excavation working face and the harmful gases and dust produced after blasting, and create good climatic conditions, the excavation working face must be ventilated. This ventilation is called local ventilation or excavation ventilation. There are three main methods of local ventilation: ventilation using the full wind pressure of the mine, hydraulic or compressed air ejector ventilation, and local fan ventilation refers to the method of ventilating the excavation tunnel using local fans and air guide tubes. Local fan ventilation is a kind of excavation ventilation method widely used in coal mines in my country, which can be divided into three types: pressure type, extraction type and mixed type.
