These are the main advantages and disadvantages of limestone quarrying….Quarrying.
| Advantages | Disadvantages |
|---|---|
| Vital building material | Destruction of the landscape, as well as the wildlife habitats within the landscape |
| Provides employment | Regular blasting produces excessive noise and dust |
Is it bad to live near a quarry?
Those living or spending time near the quarries or the roads with the diesel-truck traffic face exposure to higher levels of particulate matter and may face higher health risks (18, 21–22).
What are disadvantages of limestone?
Disadvantages
- Limestone, cement and mortar slowly react acid rain and wear away, this damages walls made from limestone and it leaves gaps between bricks.
- Concrete is weak when bent or stretched.
- Some people think concrete building and bridges are unattractive.
- Glass is brittle and easily shattered.
What is the weakness of limestone?
This rock has already a brittle structure, which causes break-ups and dissolves. Inherent weakness in the stone itself or the gradual breakdown of the binder used for building it and the external factors are the main reasons which affect the durability and strength of the limestone and which finally cause crumbling.
Is it noisy living near a quarry?
But if you live close to a hard rock quarry, you may notice occasional noise or vibration arising from quarrying activities. Apart from vibration, the energy used in blasting to move and break rocks may also result in some noise and dust. The further you are away from the quarry, the less you will notice these impacts.
What are the problems caused by extracting limestone?
Quarrying creates pollution from noise and dust. Heavy traffic causes pollution and congestion on narrow country roads. The vibrations from heavy traffic can cause damage to buildings. Quarries create visual pollution and tourists may be deterred by the scars on the landscape.
Are quarries loud?
The type and number of possible noise sources will vary depending on the nature and size of the quarry but noise may arise from the operation of mobile equipment within the quarry as well as the extraction process, which may include blasting. The crushing and screening processes may also be potential sources of noise.
What is the benefit of a quarry?
The most common purpose of quarries is to extract stone for building materials. Quarries have been used for thousands of years. Ancient Egyptians built the Great Pyramids with massive limestone and granite blocks cut by hand from nearby quarries. Each of these blocks weighs many tons.
What are the health effects of quarrying limestone?
Quarries may have a negative health impact. Stringent health and safety regulations can offset some of the negative health impacts that quarrying limestone may cause, but not all of them. Inhaling the dust from a limestone quarry is known to cause silicosis and pneumoconiosis.
How much does it cost to use quarried limestone?
It is extremely affordable. Compared to other building materials, the cost of quarried limestone is much lower than most options. A 50-pound bag of limestone chips, for example, can be purchased for around $30. Limestone pavers are about $300 per every 100 square feet of coverage.
How is limestone used as a natural resource?
Limestone is one of the most valuable natural resources known to man. Limestone is used for a plethora of purposes, most importantly to make concrete and glass. The method used to extract limestone from the earth’s crust, which includes the topmost surface of the various layers of soil, is known as quarrying.
What kind of jobs are there in quarries?
Quarries can provide numerous jobs at the local level. People can work at the quarry to extract the limestone that is needed. Drivers are needed to transport the limestone to where it will be processed or used. Processing facilities hire handlers to create usable products from the delivered materials.
