Abstract

The invention discloses a mine ventilation system comprising a wind supplying well, a plurality of wind supplying roadways, a plurality of wind returning roadways and a wind returning well. The wind supplying well is used for supplying wind to a down well, and a main wind supplying fan is installed in the wind supplying well; the wind supplying roadways are connected with the wind supplying well, subsidiary wind supplying fans are installed in the wind supplying roadways, and a wind inlet adjusting damper is installed in the connection position of the wind supplying roadways and the wind supplying well; the wind returning roadways and the wind supplying roadways are corresponded one by one, non-return valves are installed between the wind returning roadways and the wind supplying roadways, and subsidiary wind returning fans are installed in the wind returning roadways; and the wind returning well is used for exhausting out circulation air in the down well, and a main wind returning fan is installed in the wind returning well. The mine ventilation system and control method thereof can overcome the shortcomings of the prior art and improves the ventilation effect of the mine ventilation system.

Description

technical field [0001] The invention relates to the technical field of mine ventilation, in particular to a mine ventilation system and a control method thereof. Background technique [0002] Mine ventilation system is to send the fresh air on the ground directly or after being processed by mechanical ventilation, and send it to the underground operation site through the air inlet shaft, dilute the dirty air in it, and then pass through the return air shaft directly or after air treatment Emissions to ground atmosphere. Its basic function is to provide clean air for people to breathe, dilute and eliminate harmful gases and dust generated in the production process, remove excess heat and humidity, and create a production environment suitable for human operation. Therefore, rational construction and management of a ventilation system is not only the basis for creating safe production and sanitary conditions, but also an important means to prevent various disasters, which is o...
