摘　　要：某矿业公司尾矿管道输送项目投入运行后产生低频噪声,诱发尾矿输送泵站周围民居的大门、玻璃窗、吊顶产生共振。从噪声频谱特征、建筑结构振动安全性、噪声源模拟、住宅建筑室内噪声振动4个方面分析,发现居民建筑物共振主要由尾矿输送泵站直线筛产生的低频噪声诱发共振导致,厂界噪声及敏感点噪声超标主要由民居大门、玻璃窗、吊顶共振导致。通过隔声吸声的噪声控制措施,消除了周围民居大门、玻璃窗、吊顶共振现象,尾矿泵周围民居噪声敏感点、厂界的环境噪声昼间小于60 dB(A)、夜间小于50 dB(A)。A mining company tailings pipeline conveying project was put into operation to generate low frequency noise,which induced resonance in the doors,glass windows and ceiling of residential buildings around the tailings con-veying pumping station.The study from the noise spectrum analysis,the structure of the building vibration safety analysis and simulation analysis,the residential building indoor noise vibration,four aspects analysis found that residents building resonance was mainly due to the linear sieve of low-frequency noise induced resonance,noise and sensitive noise at boundary of overweight was mainly due to the residential doors,windows,ceiling cause resonance noise.Through noise control measures of sound insulation and sound absorption,the phenomenon of surrounding residential gates,glass windows and suspended ceilings had been eliminated,and the ambient noise of residential noise sensitive points around the tailings pump and the plant boundary was less than 60 dB(A)during daytime and 50 dB(A)during nighttime.
