串联通风是煤矿开采采区接续过程中经常被采取的一种临时性措施,这就难免给被串作业面入风流带来污染,风流中粉尘质量浓度高,有毒有害气体多,严重危害机械的运行及职工的健康。文章探讨了基于PLC自动控制技术的防尘措施。经验证,其效果显著。 Tandem ventilation is a kind of temporary measure often taken in the continuous mining area of ​​coal mining, which inevitably brings pollution to the wind flow in the string work. The dust concentration in the wind flow is high, there are many toxic and harmful gases, which seriously endanger the mechanical Operation and staff’s health. The article discusses the dust control measures based on PLC automatic control technology. Proven, the effect is significant.
