摘 要:分析了兴隆庄矿主扇噪声的特点及居民楼内振动强烈的原因。根据噪声特点及治理的特殊要求,设计了一套综合降噪方案:将出风口加高并在其内部用吸声砖砌成阻抗复合式消声器;机房加装隔声门窗,竣工后实测表明,该工程减振降噪效果显著。The main fan noise features and strong vibration reasons in the residential building at Xinglongzhuang Coalmine are analyzed.Based upon the noise features and special administering requirements,a set of noise reducing scheme is designed:the outlet is height-increasing,the interior uses noise-absorptive bricks to construct a resistant complex type silencer;the machine room is additionally installed a noise insulating door and windows.After construction,the practical measurement shows that the engineering vibration-reducing and noise-reducing results are outstanding.
