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.
What are the advantages of underground mining?
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining
How is sphalerite mined?
Galena is commonly mined from sulfide deposits containing more than one mineral, often in combination with for instance Sphalerite.The most common method of excavation is Cut-and-fill mining Underground.
How do people extract opal from earth?
Opal is typically extracted from the earth through open-cut mining or underground mining methods. Miners use heavy machinery to remove overburden and dig into the opal-bearing layers, where they extract the opal-bearing rocks. These rocks are then processed to extract the opal gemstones.
Is onyx open cut mined?
Yes, onyx is typically open cut mined using traditional mining methods where the stone is removed from the earth's surface with heavy machinery.
Is open cut mining safer compared to underground mining?
Yes.
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.
Why is open cut mining safer than under ground mining?
Because there is no roof to support in an open cut whereas in underground mining there may be a very large overburden load leading to very high stresses in the tunnel roof. This may require support and there is the potential for a roof collapse to occur.
Where do you find zinc most common in underground or open cut mines?
Zinc is commonly found in underground mines rather than open cut mines. This is because zinc deposits are often found deeper underground, requiring tunneling to access the ore bodies. Additionally, underground mining methods are typically more cost-effective for extracting zinc compared to open-cut mining.
What are the advantages of underground mining?
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining
What is mining that involves excavating from the surface?
Open cut mining
What can you do to reduce open cut mining?
put a plaster over the open cut
What are the economic benefits of underground mining?
although it costs a lot, unlike an Open-Cut mine, it doesn't waste the land as much. Because all of the soil and gravel that the Open-Cut mine extracts, it processes with cyanide. This stuff kills the environment.
What is the difference of surface mining and subsurface mining?
Surface mining is safer and easier than subsurface mining.Surface mining does more damage to the environment than subsurface.Surface mining creates more of a mess then subsurface or open cut mining.ON TH OTHER HAND-Subsurface mining is very dangerous.Subsurface mining allows you to retreive minerals from underground.Subsurface mining requires you to go underground, where you will have very little air.
Why cant they ban underground mineing and do open cut mineing instead?
some veins are too deep to do open cut.
How is sphalerite mined?
Galena is commonly mined from sulfide deposits containing more than one mineral, often in combination with for instance Sphalerite.The most common method of excavation is Cut-and-fill mining Underground.
Is gold found in open cut mining?
I'm not too sure, but good question!
