针对选煤厂主要产生噪声的设备进行了分析,根据不同设备产生噪声的机理与频谱特性,提出了相应的噪声综合治理措施。通过在煤矿选煤厂中的实施,表明,采取综合噪声治理措施以后,整个选煤车间噪声明显降低,同时也降低了厂界噪声,保证了噪声排放达到国家标准。
According to the analysis of the main noise-producing equipment in the coal preparation plant, corresponding noise comprehensive treatment measures are put forward according to the mechanism and spectrum characteristics of noise generated by different equipment. Through the implementation in the coal preparation plant, it shows that after adopting the comprehensive noise control measures, the noise in the whole coal preparation plant is significantly reduced, meanwhile the noise at the boundary is reduced, and the noise emission is guaranteed to reach the national standard.
