Surface Mining
easier than subsurface mining
does more damage to environment
creates more of a mess
Subsurface Mining
it is very dangerous
you retrieve minerals from underground
you have very little air underground

∙ 13y ago- Surface mining is very dangerous.
Advantages:
- Subsurface mining is safer
- Subsurface mining is cheaper,
- Subsurface mining is faster

∙ 14y agoOf course, it depends what type of mining you are referring to, the location, the material, etc.
The most common and obvious advantage to any mining is purely economical- money, and whatever material is being mined (Like mining coal for fuel).
And the most significant drawback is environmental- Mining, in general, is terrible for the environment (Some types of mining more than others). However, mining usually invoves the complete destruction and devastation of whatever environment it is in. This can become very controversial, like the Cheviot mine in Alberta, Canada.

∙ 11y agoThe advantages and disadvantages of mining can be determined based on facts uncovered by scientists and by personal opinions. One definite advantage is the fact that it brings in large amount of profits for the companies doing the mining. It also provides employment for people who are unemployed in the mining regions. Mining for gold, coal and other ores are valuable because they are useful in manufacturing useful consumer products. The country will also benefit from the taxes being paid by the companies conducting the mining excavations. On the other hand there is a downside to mining. One of the main disadvantage is deforestation. Many of the forests and trees are being destroyed for the sole purpose of extracting valuable minerals. It has also caused pollution in the mining areas. The rivers and lakes are being polluted. The pollution has caused danger to wildlife and human beings that inhabit the mining regions. Mining is definitely a controversial issue and the advantages and disadvantages should always be weighed.

∙ 11y agoDisadvantages: It is harder than surface mining and it also costs more money and takes more time
Advantages: Leads to more minerals and ore, also creates less pollution.

Why opencast mining is cheaper for companies?
because opencast mining doesnt require shafts and tunnels to be built unlike other approaches such as deep mining. it is on the surface so transportation costs from underground to ground level do not exist. insurance costs for miners may be lower as there is no risk of the mine 'caving in'.
How does the amount of heat energy reflected by a smooth dark-colored concrete surface compare with the amount of heat energy reflected by a smooth ligh-colored surface?
The dark coloured concrete surface absorbs more heat energy and therefore reflects less heat energy.
How do you minimize effects of mining?
How do you minimize the harmful effects of mining?
How would the colors in a satellite image of an area compare with a color photograph of the same area?
The satellite image will have more realistic surface of the Earth compared to photograph.
Compare the causes and effects of deep currents and surface currents?
deep currents form when dense water neat the poles sinks and flows slowly along the ocea floor
What mining technique is less harmful to the environment surface or subsurface mining?
subsurface is less harmful

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?
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
What are types of minning?
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
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?
Yes
What are the surface and subsurface methods by which coal is commonly mined?
Longwell Mining and Open-Pit Mining
What kind of surface or subsurface mining was done in Leadville Colorado?
molybedenum
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
What is subsurface mining?
Subsurface mining, is the extraction of ores and minerals, which lie underground.
Describe 2 ways to reduce the effects of mining?
Stop using explosives, stop surface and subsurface mining, and start recycling
