Exhaust fan for mining is a tool used in the mining industry, because the working environment in the mine is dark and humid and very prone to explosions and other accidents, so the mine needs fans to carry out related work to ensure the safety of underground work.
Mine air refers to the mixture of fresh air from the ground and harmful gases and floating and sinking generated underground, its main characteristics are:
1. The oxygen concentration decreases and the carbon dioxide concentration increases;
2. Mixed with various harmful gases, mainly carbon monoxide, hydrogen sulfide, sulfur dioxide, carbon dioxide and biogas and other toxic and harmful and explosive gases;
3. Mixed with coal dust and rock dust;
4. The temperature, humidity and pressure of the air change. Under normal circumstances, the temperature rises in winter and decreases in summer; Increased humidity, higher relative humidity; In press-in ventilated mines, the pressure becomes greater; In extractive ventilation mines, the pressure becomes less.
What is a mining fan?
Exhaust fan for mining is a special mining fan, suitable for working in dust, smoke, wet mines, so mining fans can also be called mining fans, mining fans.
