What are the two main types of mining and how do they differ?
The two main types of mining are surface mining and underground mining. Surface mining involves extracting minerals or resources from the Earth's surface, while underground mining involves extracting resources from beneath the Earth's surface. Surface mining is generally more cost-effective and less dangerous, but it can have a larger environmental impact compared to underground mining. Underground mining, on the other hand, can be more expensive and pose greater safety risks, but it is less disruptive to the environment.
What are two main types of mining and how do they differ?
What are two main types of mining and how do they differ? Open cast mining, and underground mining. The reason they differ, is because underground mining is where they create shafts that lead to ore beds. Open cast mining, is the opposite of underground mining. I really hope this answer is useful! I love to help people get better at science. I hope I helped you guys! Bye.
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 might surface mining be less risky for miners than underground mining?
Surface mining is often less risky for miners than underground mining because it is conducted in open pits or quarries, reducing the risk of cave-ins or tunnel collapses. Surface mining typically involves less exposure to hazardous gases and chemicals that are common in underground mines. Additionally, surface mining operations are generally more mechanized, reducing the need for as much manual labor in potentially dangerous conditions.
What destroys more habitats underground mining or surface mining?
Surface mining typically destroys more habitats than underground mining because it involves the removal of large amounts of topsoil and vegetation. This can result in significant disruption to the local ecosystem, including habitat destruction for wildlife. Underground mining, on the other hand, has a smaller surface footprint and may cause less direct habitat destruction.

How is surface and underground mining different?
Surface mining is used where the ore or material to be extracted is located fairly close to the surface. The overlying ground cover is removed, the material is mined, and the ground cover is ordinarily replaced. Subsurface mining is used where the material is in veins deep beneath the surface, or obstructed (by rock layers, water tables, or other strata) in a way that make surface access impractical. Early mines used existing caves, but technology has brought increasingly deep and complex drilling to reach veins of coal or metal ores.Surface MiningSafer and easier than subsurface mining.Does more damage to the surface ecosystems than subsurfaceCreates more of a mess than subsurface or open cut mining.Subsurface MiningNot as much widespread damage to ecosystemsDifficult and expensive to digVery dangerous conditions can include collapses, released gases, particulates in the air, low oxygen, and heat
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.
Why do they mine underground instead of above ground?
Mining underground provides access to deeper and richer mineral deposits that are often more valuable. It also allows for better control over ventilation and environmental impacts compared to open-pit mining. Additionally, underground mining can be safer for workers as they are protected from surface hazards and inclement weather.
What are two ways to mine coal?
Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining.The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.
What are the disadvantages of underground mining?
Underground mining is very expensive to conduct. It requires management of a fresh air supply, along with drainage. Underground mining can only remove a portion of the mineral present (the rest is holding up the roof). You could get trapped and die.
Is it dangerous mining gold?
Mining is potentially a very dangerous occupation, however, with the health and safety rules in place in most Western countries these risks are well managed. Firstly, are you talking about open cut or underground mining? Depending on the nature of the gold deposit this will dictate the mining method used to extract it. This may range from large open cut operations to small narrow vein airleg mining which is performed underground. Obviously, underground is potentially a more dangerous environment due to the potential for rock falls, equipment fires and even gas explosions (in some mines, not all). Compared to coal however, many consider hard rock mining (ie: gold, nickel, zinc, copper etc) to be far safer due to the fact that metal deposits tend to form in hard rock environments, whereas coal is a sedimentary deposit and is softer. This means that coal mines have a higher potential for roof (or 'back' as we say in metal mining) failure. Actually, in longwall mining for coal the roof is designed to collapse behind the mining front. Underground workings are supported with steel bolts and mesh to prevent them caving which is crucial to stability underground. So generally, wherever you are underground the risk of rock fall is minimal...as long as you NEVER walk under unsupported ground...a BIG NO NO IF YOU WANT TO LIVE. Before you work underground you will receive induction training and what to do in case of emergencies etc. It may seem scary at first but it is very exciting working underground, and the guys on your crew will look out for you as a new guy. That's what is so cool about mining, there is a lot of camaraderie on the mines, a great working environment. So, basically, there are obvious risks in mining especially when you have such large machinery in enclosed spaces, explosives to play with, blasting hauling etc etc. But with some decent initial training, working safely and looking out for your crew mates there is no reason why mining should be any more dangerous in reality than other professions. Comments are based on my experience as a miner/mining engineer working in underground nickel, gold and coal mines
Why do we use underground mining?
Underground mining is used to extract valuable minerals or ores located deep beneath the Earth's surface. It is often the only feasible method to access mineral deposits when they are located too deep or when surface mining methods are not suitable due to environmental concerns or safety reasons. Underground mining also allows for the extraction of minerals in a more controlled and efficient manner.
