摘要
本文以某煤矿风井为研究对象,该煤矿对风井处进行了现状和噪声源噪声监测,在采取了具有针对性的综合降噪消音措施后,经过监测,该风井厂界噪声均能满足《工业企业厂界噪声标准》(GB12348-90)中Ⅱ类标准,做到边界噪声达标排放。
We monitored noise of environment and air shaft,found out that boundary noise meet Ⅱdegree of "Standard of noise at boundary of industrial enterprises"(GB12348-90)after noise reduction measures were taken.
