The mine operator must establish and implement a safety management system before mining operations take place. The safety management system must manage all aspects of risks to health and safety, in relation to the operation and have appropriate regard to the nature, complexity and location of the mining operations.

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):

Noise mitigation and best practice. By Dr Paul Cockroft, senior partner, WBM Noise Consultants. Noise control at quarries is required to address two main issues: first, the effect on the hearing and general well-being of employees and visiting personnel within a site; and secondly, the environmental noise that may affect people living in the vicinity of a quarry and other adjacent potentially ...
Geography, geology and the type of stone mined, how close a quarry is to neighbors, the size of the operation and the main transportation method used to get the stone products to customers all have an impact on how each quarry is designed and operated. At Vulcan Materials Company, our primary business is quarry mining.
Jul 11, 2018· Over 90 percent of this water flows (often underground) through Comal County. Since the proposed quarry site is in the Edwards Aquifer Recharge Zone, a high potential exists for water contamination from silt, oils, chemicals, and hazardous waste from the mining process. For aggregate mining, the primary way of suppressing dust is water.
Any hazard or potential hazard should be considered significant or potentially significant if such a failure would directly or indirectly, be liable to endanger premises, roadways or other places where people are likely to be found offsite; or likely to cause serious or fatal injuries to persons on or off-site.
Jun 24, 2020· Several people said the noise and dust created by blasting, excavating and trucking stone from the open pit mine would intrude on the adjacent park .

: Study on Noise Levels Generated due to Jack Hammer Drills in Granite Quarries distance increased the noise level decreased. Variation in noise levels at the distances might be due to rock properties. The results also agreed with Roy and Adhikari[10]. The safe zone for each quarry was determined by extending the trend line on x-axis (Table 2).
Introduction. Although quarry operations have high economic significance, the effects they cause to the workers in terms of excessive noise production cannot be overlooked. This cross-sectional study assessed the extent of noise exposure and its influence on hearing capabilities among quarry workers in Ashanti region. Methods . The study involved 400 workers randomly selected from five ...
Furthermore, no study has focused specifically on occupational hearing loss among workers of quarry industries even though the impact of noise pollution on hearing in mining company has been studied . This study seeks to provide empirical evidence on the extent of noise exposure and its influence on hearing capabilities of workers in the quarry ...

From what we learned so far, we can say that mining is a very high risk business, from both the safety and economic point of view. Slope stability is one of the major sources of risk, and hazards arise in several ways, from an incomplete knowledge of geological conditions, and an incomplete knowledge of damage caused by mining processes, or an ...
The noise is now being recognised as a major health hazard; resulting in annoyance, partial hearing loss and even permanent damage to the inner ear after prolonged exposure. The problem underground is of special importance because of the acoustics of the confined space. The ambient noise level of the underground mining area is affected by [.]
Assess the risk using noise risk matrix on the next page. Identify your noise in decibels (dB) and plot against the time of exposure. This will determine your risk rating5. Example: When drilling in either an open cut or an underground environment. The drill noise emission has been measured and it has been determined that the equipment emits 94dB.
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.
Noise-induced hearing loss is the most common preventable occupational health condition in the world. Noise is defined as 'unwanted sounds', while sound is a term used for sensation that the brain receives when pressure variations in the air are detected by the ear.

So, a quarry is any such working on the surface of the earth where minerals are extracted. Quarries are also known by other names around the world: 'surface mine', 'pit', 'open pit' or 'opencast mine'. Within the UK, the largest quantity of mineral extracted by quarrying is used .
