煤矿企业球磨机机房噪声分析与治理

Analysis and Control on Noise of Cylinder Room in one Coal Mine

根据某煤矿球磨机机房的噪声污染状况的现场调查,结合球磨机机房噪声的特点,采用沈阳工业大学振动噪声研究所方案,采用隔声罩、声屏障、吸声体等防护措施,对球磨机机房噪声进行分析和综合治理。

Based on the investigations of noise pollution in the cylinder room of one coal mine and the characteristics of the noises in the cylinder room,the noises are analyzed and a comprehensive noise control program is carried out by adopting the scheme provided by Vibration and Noise Research Institute of Shenyang University of Technology,in which some protection measures are utilized,including acoustic insulator,acoustic absorption body and sound barrier.
