3. The Environmental Impacts of Aggregate Extraction

Of course, each pit or quarry has unique characteristics and impacts, but every pit or quarry will degrade the natural environment. For pits or quarries situated on lands designated as ecologically significant, this degradation has an even greater adverse impact.

Hydraulic Impacts of Quarries and Gravel Pits

At all three sites, the quarry dewatering has altered the local ground-water hydrology. In essence, the quarries act as huge wells, lowering the water table in the aquifer. The impact of the dewatering at the Kraemer Quarry is shown in Figure 2. This lowering could affect Figure 2. The impacts on ground-water levels of drawdown at Kraemer Quarry.

The Hazards of Dust from a Pit/Quarry Operation

In the light of these known hazards from gravel dust it is essential that evidence is available (perhaps from existing gravel quarries) of the extent to which PM 10 and PM 2.5 particles of crystalline silica dust can be expected to be found (say over the course of a year) at distances of say one, two and four kilometres from quarry workings

DECLINING PROPERTY VALUES: The negative impacts on local property values of a new quarry operation in a community are clear and irrefutable. The reduction in value of properties are significant, as high as 25% or more, and are irrespective of whether a local resident actually sells his or her property.

Quarry Facts

Property values drop when a quarry is built. Over the past twenty years, the evidence is clear. Scientific methods have been developed to account for other factors such as the size and location of the property, the local environment, age of the house etc., so that the effect of property value changes caused only by the quarry can be calculated.

Eventually this layer will erode, but it is generally hoped that the rate of leaching or acid will be slowed by the cover such that the environment can handle the load of acid and associated heavy metals. There are no long term studies on the success of these covers due to the relatively short time in which large scale open pit mining has existed.

Health Hazards of Mining and Quarrying

The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation. These occur in varying combinations depending on the mine or quarry, its depth, the composition of the ore and

Reading: Open-Pit Mining Geology

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is

What is Quarrying?

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

Environmental Effects of Sand and Gravel Mining on Land

The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur. This study was carried out to determine the environmental effects of sand and gravel mining in Luku, North central Nigeria, using field observations and laboratory analysis of soil samples.

In other words a quarry is a big man-made hole in the ground from where minerals or rock are taken out. Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining.

Environmental Risks of Mining

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

3 Technologies in Exploration, Mining, and Processing

Quarrying is similar to open-pit mining except the term is commonly applied to the extraction of dimension stone and aggregates. Fewer benches are required in quarrying than in open-pit metal mining ( Figure 3-4 ); in quarrying, most of the material extracted is marketable.
