移动式凿岩机隔声操作室在某地下开采矿山的应用实践

Applicaiton of Mobile Rock Drilling Machine Noise Controlling Room in an Underground Mine

职业性噪声聋是指人们在工作中长期接触生产性噪声而形成的一种进行性感音性听觉障碍。职业性噪声聋患者与其接触噪声的时间、强度,特别是噪声作业工龄有极大关系。以某地下开采矿山为例,采用移动式隔声室对该矿井下凿岩机的工作噪声进行治理,并对移动式隔声室的具体技术参数和功能进行了探讨。现场实践表明:使用移动式隔声室后能够有效降低现场作业人员的噪声伤害,对于地下开采矿山噪声防控具有一定的借鉴价值。

Occupational noise deafness is a kind of hearing disorder characterized by sexual sounds formed by exposure to the productive noise over a long period of time during the working process.The time and intensity of exposure to noise,especially for the working yeares of noise are significantly related to occupational noise deafness.Taking an underground mine as the study example,the working noise of the underground rock drilling machine is treated by mobile noise controlling room,and the pecific technical parameters and functions of mobile noise controlling room are discussed.The field practice results show that the noise damage can be significantly reduced by using mobile noise controlling room,it can provide reliable reference for noise controlling of underground mines.
