els encountered in the open cast mining industry are sec-ond only to that encountered near jet engines at airports [3]. Noise-induced hearing loss usually occurs initially at high frequencies (3k, 4k, or 6k hz), and then spreads to the low frequencies (0.5k, 1k, or 2k hz) [4]. Sources of Noise noise, defined as undesirable sound, is a by-product

A recent systematic review on the management of occupational noise-induced hearing loss (ONIHL) in the mining sector in Africa between 1994 and 2016 revealed that there is a dearth of research …

Australian mining industry. These shifts involve greater risks to workers' hearing than indicated by the noise exposure level of L. Aeq,8h. The noise exposure of workers engaged in duties on extended work shifts (L. Aeq,T, where T is equivalent to the time exposed) should first be normalised to an eight hour exposure, before

Air, Noise, Soil Pollution in Mining and Ore Processing Industry. An important part of the economy, mining & ore processing provides the raw materials for a broad variety of goods & materials. It is necessary to mine metals since they may be used in many different items. The extraction of ore, metals, minerals, and jewels from the earth's ...

Noise and acoustic microclimate have an important influence on working conditions in industry. However, there are many sources of noise in machinery that create occupational hazards.

Mining has affected the local environment and associated biota through the removal of vegetation and topsoil, the displacement of fauna, the release of pollutants, and the generation of noise. Mining of coal, both surface and subsurface, causes enormous damage to the flora, fauna, hydrological relations, and soil biological properties of the ...

The mining industry is an important source of noise for wildlife, and the eastern blue-tongued (EBT) lizard (Tiliqua scincoides) is an Australian animal that may be impacted.

Noise pollution in coal mines is of great concern. Personal injuries directly or indirectly related to noise occur from time to time. Its effects impact the health and safety of coal mine workers. This study aimed to identify if and how the level of noise impacts miners' safety behavior in underground coal mines. In order to study the influence of …

Noise in mining can come from a whole host of sources across a site, making the hazard difficult to manage. Whether the culprit be processing plants, machinery, traffic, blasting, or otherwise, a mine site is an …

The management of noise from mining operations is a fundamental responsibility of mine operators. Noise level monitoring is one method used to assess the potential for hearing loss among workers and to determine whether noise mitigation measures are effective. Solutions such as sound attenuation can allow for extended operating hours, increased ...

In the mining industry, noise pollution is not a new concept. The mining community has the highest and persistent hazardous level of noise exposure to which workers are exposed when compared with other industries. ... This is due to various noise sources in mines, e.g., excavators, dumpers, dozers, loaders, drilling machines, …

Abstract. Noise emissions are a significant environmental impact caused by the mining industry in all technological phases of surface mining, mineral processing, and waste disposal. This paper presents the …

Repeated noise exposure and occupational hearing loss are common health problems across industries and especially within the mining industry. Large mechanized processes, blasting, grinding, drilling, and work that is often in close quarters put many miners at an increased risk of noise overexposure. In stone, sand, and gravel mining, …

Noise pollution in the surrounding mining areas or construction sites within variety of equipment causes by several sources of noise such as processing plants [16], blasting and machinery [17 ...

Loud noise creates a range of health effects, of which the most obvious one is noise induced hearing loss (NIHL). According to Safe Work Australia (2013) in 2010-11, one quarter of workers' compensation claims for miners was for deafness. Another common auditory effect associated with loud noise exposure is tinnitus (ringing in the ears).
