摘要
针对煤矿通风机原有噪声治理的不足,分析噪声机理,认为空气动力性噪声和电机噪声是主要噪声源,根据国家标准和该矿实际,制定噪声治理设计原则,应用隔声和消声控制理论,采取可行、高效的措施进行治理,并经检测,证明该治理实用,可行、效果好,有推广应用价值。
Based on the disadvantages of the control over the noise from the ventilator in the coal mine,the paper analyzes the reasons and finds that the main noise sources are the active noise from the air and noise from the machines in the mine.According to the national standard and the reality of this mine,this paper puts forward the principle of noise-controlling design,which is to take practical and effective measures by the application of the noise separation and elimination theories.It proves to be practical and effective and worthy of being popularized.
