Torr Quarry has been active since the 1940s, covering 2.5 square kilometers near Shepton Mallet, with a current production of around 5 million tonnes of limestone, mostly used in road construction and transported by rail to the southeast. The quarry focuses on environmental sustainability, including creating wildlife-friendly lakes, landscaping ...

As a former environmental health and safety officer, she says the proposed granite rock quarry would impact where she lives. "We're looking at air, water, and noise issues," Deckert says.

Causes and Effects of Climate Change. Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas ...

Daily Updates of the Latest Projects & Documents. Bhutan's natural environment is among the most pristine in South Asia. With a stellar performance on sustainability and carbon neutrality, Bhutan is a recognized global .

The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth's atmosphere. Greenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gases.. Greenhouse gases allow the sun's light to shine onto Earth's surface, and then the …

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 operation and, assess the efforts towards minimizing environmental impacts of their operations. Primary data used for this study was …

This work is the first attempt to quantify the efficiency of blasting operations in the aggregate quarry by combining the fragmentation produced and the resulting environmental hazards in a single ...

The effect of quarry rock dust and marble sludge powder on the compressive strength and split tensile strength were recorded at the curing age of 7 and 28 days. All the data are tabulated and compared. It was observed that particular proportions of marble sludge powder and quarry rock dust displayed enhancing effect on the compressive strength.

All quarry operators must submit the production and operations data to the local competent authority and to technical division of the ministry of environment and water (MOEW-TD). 5.1 Monthly production data showing separately, all the types of materials (armor rock, graded rocks of different sizes, aggregates, sand, road base, etc.).

The dimensions of the hypothetical models were considered 2 m in the x direction (cutting depth of the quarry face), 20 m in the y direction (quarry face length), and 4.5 m in the z direction ...

This study evaluates the impacts resulting from quarry-blasting operation on nearby buildings and structures as it generates ground vibration, air blast, and fly rocks. In this paper, first blasting operation and its possible environmental effects are defined. Then the methods of blast-vibration prediction and commonly accepted criteria to prevent …

Whilst a quarry is in use the effects on the local environment are more than just the loss of wildlife habitats and the obvious visual impact. A working quarry needs methods of transportation and this means that large amounts of machinery and heavy traffic will be brought into the area, causing an increase in local noise, pollution and erosion.

Mitigation of environmental impacts in ornamental rock and limestone ...

The effects of quarries on both the environment and human beings have been proven. Blasting, crushing and emission of noxious gases cause air pollution and ground vibration, which can, as a consequence, have negative impacts on people's health and well-being. In Fujairah, a quarry in Al Taween has caused distress to some residents, many of ...

The experimental blasts carried out in Trebejov Quarry proved that the reduction in the vibration intensity under the value 2 mm.s 1 led to the satisfaction of the inhabitants. Keywords: blasting works; seismic effects; milliseconds timing interval; the internal environment of buildings; ground vibration; environment; mining; blasting work in ...

What are the effects of global warming? One of the most concerning impacts of global warming is the effect warmer temperatures will have on Earth's polar regions and mountain glaciers. The Arctic ...

2.9.1.1. Impact of noise The visual effect rock quarrying has on the environment however temporary; the most complained about consequence is noise according to Good Quarry. Blasting is a common technique used by miners to loosen stone for quarrying. Blasting involves the use of heavy explosives and has drastic impacts on the immediate …

watersheds. Minimizing environmental impact is therefore a fundamental requirement for the sustainable operation in the cement sector. Impacts can be successfully addressed and mitigated through the development and implementation of an effective quarry rehabilitation plan and a Biodiversity Management Plan, especially in areas of

The hydrogeological effect of limestone extraction from open pits (quarries) depends on the location of the site in the landscape, the vertical and horizontal extent of the excavation, the methods ...

This study tried to identify the environmental effects of quarrying in the identified quarry sites of Region 1 chosen at random, specifically at a geologic perspective.
