摘要
煤矿局部通风机(简称局扇)的噪声是煤矿掘进中的主要噪声源,分析了局扇噪声产生的机理,综述了从局扇的噪声源和传播途径上控制噪声的方法,为局扇的降噪提供了有益的参考。
The noise produced by partial auxiliary fans in mine is the main resource of noise. The producing mechanism of noise from auxi - liary fans is analyzed and the methods of controlling noise is described from two aspects of noise resource and transmitting ways in this paper, which offers beneficial reference for the reducing of noise from partial auxiliary fans.
