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
Underground mining operations attempt to follow the course of a valuable ore deposit as it winds its way in three dimensions underground. The opening into the mine may be a relatively small opening on the surface, big enough for the passage of miners and the ore they are retrieving.
Open pit mining involves the surface removal of material which lies over the ore deposit, and the extraction of the ore with the use of explosives and excavation equipment, as well as its transportation with large wheeled machinery to an area of processing. This type of mining is more cost-effective for near-surface ore deposits.
This mining method allows easy access to the preferred minerals and ease the extraction of this mineral due to the direct exposure
Open-pit mining is a technique that is used to extract rocks and minerals form the earth.
Uranium mining can be either by open pit mining or by underground 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
This would be underground mining.
Real is what is fetched from mining and created is which is composed in a lab.
The open pit mining or the underground mining are more common now.
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
difference between Data Mining and OLAP
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
Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
Strip mines,Openpit mines & shaft mines
it is open not underground (it has no roof)
Underground mining surface mining
underground 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.
Yes. This is correct, but next time you might want to check your k12 earth science book for help. =)
it is, because if underground the mine can cave in.
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
