Research on the Negative Pressure Monitoring Alarm System of Main Ventilator in Coal Mine

井下通风系统是否正常、风量是否达到要求,主要通过监测负压变化来实现的,主通风机负压大小值需要依靠司机频繁观察U型压力计或负压传感器,比较繁琐。介绍了主通风机负压异常声光报警装置,希望能更好地提高煤矿主通风机负压监测系统的安全可靠性。

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.
