Blasting operations can cause excessive noise and vibrations. Noise from blasting is a significant factor and can be disturbing to neighbouring residents or other workers in the area. It is the leading element for blasting complaints in Queensland.
A mobile application associated to this monitoring station facilitated the quarry's manager and employees to ac-cess immediately the monitoring information. There-fore, by using this system, it was possible to evaluate the effectiveness of noise reduction measures already taken and indicate what steps still need to be held.
This paper addresses the issue of environmental noise from mining operations, focusing on the specific case of a quarry located in the municipality of Trebejov, Slovakia.

P art 1 of this blog article discussed the importance of environmental (community) noise, what cement plant operators should know about noise limits applicable to their plant, and considerations with respect to environmental noise during the design of a new or expanded plant. Part 2, below, discusses how to address noise complaints, the …
This article explains the effects industrial noise has on local mining communities, the health concerns, the importance of mitigating risk, and what individuals can do if faced with this issue.
The insatiable demand for rock supplies has enticed numerous building and construction enterprises to participate in stone quarrying. However, this has had an environmental impact on air quality. This paper examines the environmental impact of quarrying on air quality in Ebonyi State, Nigeria. To achieve the main aim of the study, an …
Some quarries already achieve almost dust control, believes Ossevorth, but many others could reduce their dust emissions by about 50%, though it could be quite expensive to do. He said that typical quarries in Germany have been suffering from a lack of money available for investment in recent years.
The Rock Hill Quarry, owned by Hanson Aggregates PA, LLC, located in East Rockhill Township, Bucks County, has been active since it was first permitted in 1976. In 2017, R.E. Pierson was awarded a contract from the Pennsylvania Turnpike Commission for turnpike construction projects and was the contract operator of the Rock Hill Quarry. In May …
The study investigated the environmental effects of quarry operations in Abeokuta, Ogun state, while it specifically sought to identify corresponding environmental impacts posed in quarry ...
FOUR OAKS – Johnston County Commissioners heard concerns from neighbors afraid added hours at an adjacent business will only create more noise pollution. It wasn't enough to stop the majority of the board from approving the controversial permit.
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact.
Resolving explosives inefficiency. Stemming is normally a rock or sand material that is generally placed on top of the explosive in a blasthole. Many blasters use stemming, as it can reduce the air …
Mining can create significant noise and/or vibration through blasting in both open pit and underground mines; ore and waste rock truck traffic on the mine site; ore stockpiling, screening, and crushing; and truck or rail traffic bring consumables to the mine site and shipping product from the mine for final processing.
Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal wildlife, it also leads to a huge loss of biodiversity as plants and aquatic habitats are destroyed. Moreover, adjacent eco-systems are affected by noise, dust, pollution and …
The explosives are then detonated in a precise sequence, designed to maximise the efficiency of rock breakage while minimising noise, vibration and dust. One of the advantages of blasting is that it reduces the need to operate large heavy equipment to extract the rock, in turn reducing noise and greenhouse gas emissions.
The Quarry Quandry. by Jim Wood September 10, 2007. Photos by Tim Porter. The San Rafael Rock Quarry is one of those places most in Marin know little about, while a few know everything about it. Located on an elbow of land jutting into San Pablo Bay, the quarry is a passing curiosity for hikers headed to China Camp State Park or …
MP11, for example, suggests that by progressively working away from the noise-sensitive locations, the noise exposure will reduce with time. Conversely, it is pointed out that if the excavation proceeds towards the noise-sensitive location, the quarry face itself can act as a noise screen. Given that the reduction of noise with distance is …
Industrial noise reduction solutions that save companies thousands of pounds on factory noise control, suppression & cancelling of machine sound.
In the following article, Josh Thomas from instrumentation specialist Ashtead Technology, discusses the risks associated with dust at quarries, and highlights the vital role of monitoring.
The Makakilo Quarry is one of only three quarries on O'ahu that can supply the quality materials needed to build roads, highways, homes and more. This local source of stone benefits the local economy by ensuring the resources necessary for public and private projects, reducing import costs, keeping the investment in Hawaiʻi, enabling on-site …
Coosa Riverkeeper is concerned about the proposed 431 Quarry near Oxford. This nearly 350 acre quarry has the potential to impact water quality, local wells, and quality of life for surrounding communities. Please read below and make your voice heard at the upcoming public hearing and/or submit comments!
However, qualms about the quarry led to the company agreeing to reduce noise in some ways, like limiting the hours and days that blasts happen.
