摘要
李雅庄煤矿井下局部通风机的恒速运转容易带来“一风吹”现象,成为了导致瓦斯爆炸事故的一个重要因素,基于该问题设计巷道排瓦斯自动调速装置。实践应用效果表明,该装置能改善井下通风环境,实现安全高效排放瓦斯。
The constant speed operation of local ventilator in Liyazhuang Coal Mine is easy to bring "one wind blowing" phenomenon, which has become an important factor leading to gas explosion accident. Based on this problem, an automatic speed regulating device for gas drainage in roadway is designed. Practical application results show that the device can improve the underground ventilation environment and achieve safe and efficient gas discharge.
