Ambient noise and dust concentrations were measured at different distances and directions from the source. The correlation between the distance and noise level as well as dust concentration were carried out to determine a safety zone from the quarry ...
Moreover, adjacent eco-systems are affected by noise, dust, pollution and contaminated water. Pits and quarries disrupt the existing movement of surface water and groundwater; they interrupt natural water recharge and can lead to reduced quantity and quality of drinking water for residents and wildlife near or downstream from a quarry site.

The study population was drawn from workers of the five (5) quarry companies, namely, Northern mine quarry, A. Kannin mine, Taysec quarry company, KAS quarry company, and Siemens quarry company. Workers who have been working at the respective quarry for more than six months were included in the study.
Title: Noise and vibration from blasting Author: Department of Environment and Science Subject: This guideline sets out performance criteria to be used when setting operating requirements in conditions of environmental authorities issued under the Environmental Protection Act 1994 (and in other approvals) for activities involving blasting, such as mines, quarries and construction.
Research found when reading the noise levels from blasting activities at quarries for ten days, the noise ranged from 102.8 to 130.8 decibels. During crushing activities, they reached between 97 and 116.2 dB – however, another study focusing on a crushing unit in Bangalore found it could range from 133 to 156 dB.

SAFETY RISK #2 - MUSCULOSKELETAL INJURIES Causes: Musculoskeletal injuries can be caused by operating heavy quarry equipment, the manual shovelling of earth, clay and shales, and the lifting and carrying heavy stones. Prevention: Good posture and lifting techniques, along with mechanical lifting aids, can help reduce the risks.
According to the United States Bureau of Mines (USBM) standard, the attenuation equations were developed using field records. A general frequency analysis and risk evaluation revealed that: 94% of generated frequencies are less than 14 Hz which is within the
Free crystalline silica and asbestos are just a few examples of airborne dust that puts these workers at risk.

For individual quarry operations, as part of their risk-assessment programme under the Management of Health and Safety at Work Regulations, 1999, health risks can be assessed subjectively. In order to be able to make an assessment of the risk of health hazards, the two major elements that need to be considered are (fig. 2):

The three major categories related to health and safety in quarrying are dust, vibration and noise. Below we take a closer look at them in more detail: Dust. A persistent and problematic presence across almost all quarry and mining sites, dust is generated at an incredibly high rate during production.
Mitigating the Negative Effects of Living Near a Quarry Noise Reduction Measures. To mitigate the noise pollution caused by quarry operations, measures can be taken to reduce the impact on nearby residents. This may include installing noise barriers or implementing noise reduction technologies on machinery and equipment.
Noise. With the constant use of heavy machinery on the site, miners are regularly exposed to high levels of noise. Unless the ears are protected, regular exposure to excessive levels of noise can cause a worker to suffer from hearing loss and tinnitus. Sleep may also be affected. Machine operators and nearby workers require ear muffs.
Noise - The revised MSHA noise standard was developed to protect miners' hearing, based on research indicating that hearing loss occurs with average sound levels below 90 dBA.

may be at risk from health hazards. When it is considered that even with control measures in place, people will still be at risk, the occupational health surveillance will only be appropriate if the criteria listed are met. Quarries Regulations 1999 In addition, the Quarry Regulations require that pre-employment medicals are undertaken. These

Noise also poses a risk and nuisance to the surrounding environment, including wildlife and nearby communities. To prevent noise-related health problems and accidents, quarry operators should take appropriate measures to monitor and minimise noise exposure and protect their workers.
