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 Mining
Subsurface Mining
Underground mining can be much more expensive than surface mining. There are limits on how much material can be removed in underground mining. Underground mining has a number of hazards not present in surface mining- so much that underground mining in the US has its own safety codes to follow.
Surface mining is a method of mining used to extract minerals and metals which are near the surface of the earth.

One is under ground, and one is on the surface.
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.
Mining techniques can be divided into two common excavation types: surface mining (above ground) and subsurface (underground) mining. sometimes subsurface mining is also called deep mining like in my text book p.s i am in 8th grade
Uranium mining can be either by open pit mining or by underground mining.
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
Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
THERE ARE DIFFERENT TYPES OF MINING SUCH AS SURFACE MINING,open cast mining, strip mining,alluvial mining,quarrying mining,underground mining,and drilling
Underground mining surface 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
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
In surface mining we dont make any tunnels. Surface mining is less risks as underground mining. In surface mining we follows the several conditions which are provides saftey.
it is open not underground (it has no roof)
Both surface and underground mining are found in Wyoming.
what are the different types of surface mining

There are a lot of different divisions. In general, you might separate them into surface mining, such as a quarry, strip mine, or open pit mine, and underground mining, consisting of shafts and adits.
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.
