Noise Pollution and Its Control in Mining

Noise known as a major health hazard is spot specific in case of underground mining where the operators are exposed to continuous background noise while high level short duration noise peaks are common in case of surface mining. The human ear is most sensitive in 2 to 5 KHz range and less sensitive in high and low frequencies.

Sources and effects of low-frequency noise

The sources of human exposure to low-frequency noise and its effects are reviewed. Low-frequency noise is common as background noise in urban environments, and as an emission from many artificial sources: road vehicles, aircraft, industrial machinery, artillery and mining explosions, and air movement machinery including wind turbines, compressors, and ventilation or air-conditioning units.

Noise Pollution - an overview | ScienceDirect Topics

Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. Abstract. Noise pollution is unwanted sound, it needs to be controlled to make the workplace comfortable. This chapter analyses noise mathematically and the effects of multiple sources are examined. Two noises of exactly the same level can have a combined noise level that is 3 dB higher than the individual values.

Noise pollution in opencast mines - its impact on human ...

[en] Noise could be defined as sound without agreeable musical quality or as unwanted sound. The problem of noise has been accentuated in the mining industry due to increased mechanisation. In opencast mines, noise is generated in almost all the mining operations, becoming thereby an integral part of the mining environment.

The model WHS Regulations, define the exposure standard for long term exposure to noise as the amount of sound energy, that is equivalent to a steady noise level of 85 decibels over an 8 hour shift. Whether this is exceeded depends on the level of noise involved and how long workers are exposed to it.
