Can you have a sentence for cheaper?
my father is cheaper than ur whole family put together.
Why did the British mining company agents want to obtain mining rights through a contract rather than taking them by force?
The British mining company agents wanted to obtain mining rights through a contract with the African king Lo Bengula, rather than taking them by force so that the rights could not be taken back or impeached.
How much does mining make?
A mining makes about more than a millon dollars a week in a year average is around one billon It also dpends on how lucky you are to find gold and rocks
What is cheaper hot air or cold air?
If it's in a car, hot air is just the engine's "spare" heat, therefore cost-free and cheaper than cold air...
Are products made in other countries cheaper than those made in the US?
Hell yeah
Why is open pit cheaper then shaft mine?
Open pit mining is generally cheaper than shaft mining because it requires less equipment and labor. In open pit mining, large quantities of ore can be extracted quickly and efficiently using heavy machinery. Also, open pit mines are typically less deep than shaft mines, which reduces the complexity and cost of excavation and support systems.
Why is surface mining cheaper?
Surface mining is generally cheaper than underground mining because it involves removing material from the surface rather than having to dig deep underground. This makes it more accessible and requires less equipment and labor. Additionally, surface mining usually has higher production rates and allows for larger equipment to be used, further reducing costs per unit of material extracted.
Why do you think that mining on land is less costly than mining in the deep ocean is?
Mining on land is less costly than mining in the deep ocean because it takes more equipment to go down to the bottom of the ocean, and all of that equipment costs more money than what they use on land.
How do surface mining and underground mining differ?
Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
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 is different deep mining and opencast mining?
rocks and minerals are easy to find and extract when they outcrop on or near the Earth's surface. All that needs to be done id to clear the vegetation and soil from the surface and start digging. Such mining is called open cast mining. deep mining involves sinking a vertical shaft down to the rock layer containing minerals, making a horizontal tunnel following the mineral layer, extracting the minerals by digging done by machines and miners, bringing the loose rock from the mine and piling it up on waste heaps on the surface and transporting the minerals. deep mining is more dangerous than open cast as miners work underground while in open cast workers work on the surface.
What mining method is used to extract ore from beneath the earths surface?
The most common mining method used to extract ore from beneath the earth's surface is underground mining. This method involves creating tunnels and shafts to access the ore body underground, where miners extract the ore using various techniques. Underground mining can be more expensive and dangerous than surface mining but is necessary for accessing deep deposits of valuable minerals.
Why is open pit best for the environment?
Open pit mining can be better for the environment than underground mining because it has a lower impact on the ecosystem and wildlife. Open pit mines generally have smaller footprints, making land reclamation easier. Additionally, open pit mining often has better air quality controls and uses less water than underground mining.
Is surface mining is less coast and inexpensive?
Surface mining is MUCH less expensive than underground mining. Usually. In some cases, underground mining is used because the substance being mined is just too deep to have a surface mine. I was just in a silver mine that is more than 5,000 feet deep. If the mine had to remove a mile of rock to get to the silver, it would not be worth mining. In THAT case, underground mining is less costly.
What are two types of coal mining?
Surface mining is used to produce most of the coal because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.In surface mining, giant machines remove the top soil and layers of rock known as "overburden" to expose the coal seam. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.Underground mining, sometimes called deep mining, is used when the coal is buried several hundred feet below the surface. Some underground mines are 1,000 feet deep. To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal.
Is underground mining more Eco friendly than open pit mining?
It depends on various factors such as the deposit type, location, and mining methods used. Generally, underground mining can have less impact on the environment than open pit mining as it requires less surface disturbance and can minimize habitat destruction and water pollution. However, both types of mining can have negative environmental impacts if not properly managed.
Why is underground mining is more dangerous than open-cut mining?
Underground mining is more dangerous than open-cut mining because it involves working in confined spaces with poor ventilation, as well as risks of cave-ins, fires, and explosions. The lack of natural light, unstable ground conditions, and the presence of toxic gases also contribute to the higher level of danger in underground mining compared to open-cut mining.
