offsite human noise receptors from mining project's noise and/or vibration. Screening is required at all new mines, and also at existing mines if there is a proposed change to the mine plan that is likely to result in a new source of noise or vibration or an increase in existing noise or vibration levels. 4.4.1.2.
NIOSH has made the reduction of noise-induced hearing loss a major strategic goal and is attacking the problem through improved noise controls and interventions for workers. The NIOSH strategy expands on decades of research by its U.S. Bureau of Mines predecessors that identified some of the key issues with underground …
For an Earthworks research project on pollution in Pennsylvania, researchers measured noise at homes near a gas processing plant and a compressor station in the 50-70 decibel (dBA) range. Researchers in West ia measured noise around several oil and gas operations, finding levels frequently above 55 dBA and some in the 70-80 dBA range.
It is in the category of the control of noise at source as shown in Figure 2. The findings of the research indicated that the mining industry perceives the buying of quitter equipment as a proactive strategy that will aid in the reduction of ONIHL, thus improving the management of noise from source.
Other sources of mining noise include ventilation fans, compressors, crushers, and grinding mills. Major extraction tools like drills or Stageloaders also generate high noise levels, operating at 90 – 110dB and haulage trucks at 90-100 dB, both operating above the 85 dB threshold generally considered safe.
Noise exposure has reached an alarming degree over the years because of rapid growth in the industry, transportation, and urbanization. Therefore, it is a dire need to provide awareness of the sources and mitigation strategies of noise, and to highlight the health, and socio-economic impacts of noise. A few research studies have documented …
Underwater noise pollution is a growing environmental problem, and in freshwater habitats the sounds produced by shipping are of particular concern. It has been shown that underwater ship noise in rivers and lakes causes stress in fish, as indicated by increased cortisol levels. Chronic physiological stress has detrimental effects on growth ...
mining industry. Hearing Loss Programmatic Areas . Develop and maintain a noise source/mine worker exposure database for prioritizing noise control technologies . Purpose: The purpose of this programmatic area is to build a database that contains up-to-date comprehensive proiles of the noise exposures to the mining population as a function of ...
For the coal mining area, the permitted noise level by the DGMS is 90 dBA. As the noise pollution with different mining operation was much above the International threshold limit and higher than even the suggested Indian standard, the following corrective measures were suggested: 1. Suitable selection of equipment with inbuilt effective ...
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 on ...
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 …
The study was conducted in an opencast mine in Central India. Sound sources were identified and noise measurements were carried out according to national and international standards. Considering ...
Unfortunately, noise and hearing loss are still a problem for today's miners. Mining has the highest prevalence of hazardous noise exposure of any major industry sector (Tak, Davis, and Calvert 2009) and mining is second only to the railroad industry in prevalence of workers reporting hearing difficulty (Tak and Calvert 2008). Noise-induced
A holistic view of the entire noise control science has three primary dimensions: (1) the noise source, (2) the process of noise propagation (transmission) and (3) the effect (response) of noise to the receiver. First-level noise control applies to the source in terms of noise engineering to reduce and eliminate noise.
The issue of occupational noise-induced hearing loss is prominent in the mining industry. Shutterstock. South Africa's mining industry has long been an important part of the country's economy ...
The mining industry, a cornerstone of modern civilisation, fuels economic growth and technological advancement. However, noise from mining operations can affect both employees and the surrounding environment, with the same noise sources contributing to both occupational and environmental noise.
Labour Health in Mining Industry, Zonguldak, 1998, pp. 73-77. [37] ... The treatment of any noise source uses any of the three basic control techniques - controlling noise at source, path or ...
Guidance note for noise measurement of equipment to ensure conformance with MHSC milestones (Kumba Iron Ore - Sishen) | (1.81 ) Guidance note For the implementation of the industry-wide buy and maintain quiet initiative (IBMQI) in the south african mining industry. | (296 KB)
Conclusion: One of the key recommendations is encouraging the South African mining industry towards the documenting and publishing of those engineering noise control methodologies that have proven ...
Since then, NIOSH has developed significant new technologies for reducing noise from continuous mining machines and roof bolting machines, which have been the main …
Mining noise is an under-reported issue. Though studies show that sounds above 85 decibels (dB) are harmful, depending on factors such as period of exposure, etc., it is still estimated that 80% of US miners work in an …
The main sources of noise in a mine are excavators, stage loaders, shearers, compressors, fans, continuous miners, pneumatic drilling machines, vibrating screens, rotating breakers and mills. The monitoring of workers' exposure to noise is an important part of the risk management process. It allows existing noise control measures …
Occupational noise-induced hearing loss (ONIHL) is the most prevalent occupational disease in the world. The goal of this study was to review the epidemiology, pathogenesis, and preventive measures of ONIHL among workers and provide evidence for the implementation of control measures. Literature studies were identified from the …
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 three most damaging sources of noise pollution in an industrial setting are machinery, construction, and vehicles. ... 20% of the sawmill workers, and 7.9% of the industry employees showed symptoms of noise-induced hearing loss. Other workers, who were exposed to hazardous noise showed clear signs of hearing impairment and other ...
Abstract. This paper surveys noise levels, noise exposure patterns, and frequency spectra found in the mining environment; the effects of mining noise on the working population; and the quantification of hearing loss in the coal mining industry. Federal mining noise regulations and the present state of the industry, with respect to noise ...
