源于机器声源的矿井掘进工作面及巷道环境噪声严重影响着矿工的身心健康,并可能掩蔽各种安全警报信号而成为安全事故的重大隐患.简要分析了典型掘进工作面机器噪声和巷道环境噪声特点,重点论述了预测与控制掘进工作面及巷道环境噪声密切相关的凿岩机器噪声辐射机理、噪声源时空特性、矿(煤)岩力学特性对机器噪声影响、巷道声学长空间环境噪声传播与衰减规律及噪声控制等领域的主要研究课题和研究进展,为掘工作面及巷道环境噪声预测与控制提供了一定依据.
The noise on mine working face and laneway brought out by drilling machine seriously influences the miners' physical and mental health,and also the noise may be a major hidden danger of safety accidents as all safety warning signal is masked by noise.This paper summarizes the noise features brought by machine on working face and laneway's environmental,and the research topics,i.e.noise radiation mechanism of drilling machine,noise space-time characteristics,the influence on machine noise from mine(coal) rock mechanics properties,noise propagation and decay laws and control in long sound space environment noise and their development status are mainly discussed,which are closely related to noise forecasting and controlling.All this work will provide certain basis for prediction and control noise in digging working face and roadway environmental.
