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
What else can I help you with?
The method of extracting minerals that involves digging beneath the surface is referred to as What mining?
This would be underground mining.
What is a method for uranium mining?
Uranium mining can be either by open pit mining or by underground mining.
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
What are the cons of surface mining?
The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground mining. * It is also faster The disadvantages of surface mining are: * That it destroys the landscape and environment * Effects the habitats of fauna potentially effecting the existing ecosystem in that area * Flora is destroyed * Causes noise, air and water pollution
How was coal removed from the earth?
Coal is removed from the earth through a process called mining. There are two main methods of coal mining: surface mining and underground mining. In surface mining, large machines remove the topsoil and rock layers to access the coal deposits, while in underground mining, tunnels are dug deep into the earth to reach the coal seams.
What is the biggest cost in mining?
It depends on the method of mining adopted. in case of openpit mines with large size fleet the biggest cost items are diesel, tyres and spares In case of manual underground mines the biggest cost items would be wages
What is the difference between OLAP and data mining?
difference between Data Mining and OLAP
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.
What are the three types of mining?
Strip mines,Openpit mines & shaft mines
Two types of mining?
Underground mining surface mining
What is Underground Mining?
underground mining is done when the rocks, minerals of gemstones are too far underground to get out with surface mining some kinds of underground mining are Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining
What is the most expensive mining?
underground mining
What are two types of mining?
The two types of mining are Open-cast mining and Underground mining. Underground mining is further divided in to Adit mining and Shaft mining.
The method of extracting minerals that involves digging beneath the surface is referred to as What mining?
This would be underground mining.
What type of mining in which passageways are dug underground to reach the ore?
deep mining
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.
