Quarries. Stone quarrying is a process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into desired sizes. This screened aggregate is then used for the construction of roads, rail lines, bridges, hospitals, schools, airports, factories, and homes, all of which has crucial impact on economic development of any country.
That can include the rugged environment of a quarry where there's always large machinery and vehicles on a site that's noisy, dusty and open to extreme weather. These factors only add to the challenge operators face in limiting visitors while enabling access for those with legitimate business. One Southeastern U.S. quarry offers a good example.

The quarrying industry is a noisy industry. The QPA3 states that typical noise levels could be between 89–108dB (A) for a primary crusher and 106–110dB (A) for hand drills. The principle health effect of being exposed to high levels of noise in the long term is noise-induced hearing loss.

Quarrying is the way toward acquiring quarry materials, for the most part, rocks found on or underneath the land surface (Banez et al. 2010).Quarrying badly affects the environment in many ways in the course of the investigation and blasting, delivering, and removal of waste rocks (Maponga and Munyanduri 1998).It is not properly controlled for environmental sustainability in most of the ...
However, some quarries have very low impact on the environment, iwi or local communities and sometimes sit idle due to fluctuations in demand such as in post natural disaster situations. To ensure the continuity of supply of aggregate, the resource management system needs to allow for fluctuating demands and periods of quarry inactivity.
