What are th two methods of extraction metals from the ore?
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
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 ways of minimizing the negative effects of mining?
1) You can return the land to its original state after the mining is completed, this process is also called reclamation. 2) We can reduce our need for minerals and recycle.
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
Quarrying and solar evaporation are included in which type of mining?
surface mining

Where is the National Mining Hall Of Fame in Leadville Colorado located?
The address of the National Mining Hall Of Fame is: 120 W 9Th St, Leadville, CO 80461
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.
What types of minnings are there?

What are types of minning?

What are someTypes of subsurface mining?
i don't know the types of subsurface mining, but i know some facts.surface mining is safer and easier than subsurface mining.You don't have much air underground.It has no or very little advantages compared to surface mining.
Is iron mined using surface or subsurface mining?
