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
Is open cut mining safer compared to underground mining?
Yes.
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 is Kalgoorlie famous for?
Kalgoorlie is famous for its rich mining history, particularly gold mining. It is home to the Super Pit, one of the largest open-cut gold mines in Australia. The town also hosts the annual Kalgoorlie-Boulder Racing Round, known for its iconic horse race, the Kalgoorlie Cup.
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.
Is gold still mined today?
Theres two main methods used to mine for gold today.Open-cut mining: In Open-cut mining, surface rocks and layers of earth are stripped away using really big shifters. Over a long period of time the mine is excavated in layers, which are known as benches.Underground mining:Underground mining is for gold's that are well below a surface. In underground mining, miners are lowered in to the shaft in large cages, in a horizontal tunnel, which is known as stopes. Stopes are dug at different depths and miner's work along these to access the gold.
What is an open cut mining different to an underground mining?
Open cut mining involves removing material from the earth's surface, using large equipment like draglines or excavators. Underground mining involves tunneling underground to access mineral deposits and is typically used when the mineral resource is deep or too dangerous to extract from the surface.
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.
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.
What equipment is used for open cut mining?
Draglines, Shovels, Trucks, Drilling Equipment, Excavators, Loaders, Components, Other
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.
