When did Victorians first use electricity?
the Victorians didn't use electricity but the light bulb did and it was the only thing that did. electricity
What is the importance in the discovery of electricity?
That you were able to ask this question. Without electricity, we wouldn't have many of the things we have now. A LOT of stuff use electricity to work.
Where did Thomas Edison invented electricity?
Thomas Edison did not invent electricity. He invented means of making use of electricity.
How does industry use electricity?
If I had to say, it would probably be the pumping of water into the building.
Which industries use the most electricity?
air conditioners
When might miners chose to use open pit mining rather than strip mining to obtain ore?
Miners might choose to use open pit mining when the ore is found near the surface and forms a wide area, making it more cost-effective to extract using this method. Open pit mining is also preferred when the ore body is not very deep, minimizing the need for extensive excavation.
What do you mean by opencast mining?
Opencast mining is a surface mining technique where minerals are extracted from the earth by removing the overlaying rock or soil. This method is used when deposits are close to the surface and involves the use of heavy machinery to extract the resources. It is also known as open-pit mining.
What type of mining can i use with an horizontal layer of coal close to the surface?
You can use surface mining methods such as open-pit mining and strip mining for a horizontal layer of coal close to the surface. These methods involve removing overburden to access the coal seam, making them suitable for shallow coal deposits.
What is the difference between open-pit mining and underground mining?
I was searching for an answer for my science homework, when I stumbled upon this answer. This was very incorrect, and I would like to fix it for you. Here is the correct answer: Open Pit Mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.Hope this helps!-Jane Derdoy
Why are open pit mining and strip mining both considered to be surface mining?
Open pit mining and strip mining are both considered surface mining because they involve the removal of ore from near-surface deposits, rather than underground mining. Both methods use heavy machinery to extract minerals or resources by removing layers of soil, rock, or other materials that cover them.
Why is open pit mining is used?
like strip mining open-pit mining involves removing the surface layer of soil. Miners then use explosives to break up the underlying rock and recover the ore. As they dig a deep hole or pit to mine the ore they build roads up on the sides of the pit. Trucks carry the ore to the surface. Ores of copper and iron are obtained by open-pit mining. (read in earth science book by Mcdougal Littell.)
How do you use strip mining in a sentence?
Strip mining involves removing the surface layer of earth to extract valuable minerals or resources. An example sentence could be: "The company plans to use strip mining to extract coal from the open pit mine."
When might you use an open pit mine?
Whenever you have a massive ore deposit (approximately 20 million tonnes or more) that is not too narrow, steeply dipping, or deep. Studies are done to determine at what depth a certain orebody is more economic to mine underground than open pit.
How are the ore deposits removed by shaft and strip mining similar to the ore deposits removed in open pit mining?
In all three methods, ore deposits are extracted from the earth for processing. Shaft and strip mining involve creating openings to access the deposits underground, while open-pit mining involves removing ore from the surface. The main similarity is that in all three methods, the goal is to extract valuable minerals from the earth for further processing and use.
What is the process called in which miners use earthmoving equipment to dig a huge hole?
The process is called open-pit mining, where miners use earthmoving equipment to extract minerals or ore from the ground by digging a large open pit. This method is commonly used for extracting minerals such as copper, gold, and iron.
Disadvantages of Open-pit mining?
Open cast mining is generally considered safer than underground mining but there are still some dangers such as: 1)Because opencast mining is done in the form of ledges one can easily fall off one of these ledges which can can meters high. 2)Because open pit mining is done using explosives it can cause injury due to flying pieces of rock and other debris. 3)Open cast mining needs a lot of space for digging and it affects the environment in many bad ways.Animals loose their homes,deforestation occurs,people have to be relocated to other places because of pollution hazards. 4)The use of explosives may also cause other accidents to happen.
How are Jade mined?
Jade is typically mined through open-pit mining, tunnels, or riverbed mining. Miners use tools such as picks, shovels, and dynamite to extract the jade from the earth. Once extracted, the jade is then processed and shaped into various forms for commercial use.
