Abstract: Negative pressure changes may be monitored to determine whether mine ventilation system is normal and whether air
volume may meet the requirements. U pressure gauges or negative pressure sensors should be often observed by driver to watch
negative pressure size value of main ventilator, which is more complicated. This paper introduced negative pressure abnormal
sound and light alarm device of main ventilator, which hoped to better improve the safety and reliability of negative pressure
monitoring system used in the coal mine main ventilator.

 Key words: main ventilator; negative pressure monitoring; alarm device
