What are the pros and cons for surface mining?

What are the pros and cons for surface mining?

Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination.

What are the pros of surface mining?

Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to 100% within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates.

What is surface and subsurface mining?

Mining is the removal of minerals from the ground. Surface mining removes ore deposits that are close to the surface, and subsurface mining removes minerals that are deep underground.

What are the negatives of mountaintop removal?

Toxic heavy metals such as cadmium, selenium, and arsenic leach into local water supplies, poisoning drinking water. This destructive practice, known as mountaintop-removal mining, sends carcinogenic toxins like silica into the air, affecting communities for miles around.

What is good about strip mining?

The coal industry contends that strip mining is the best way to supply the mineral—that stripping is more efficient, less costly and much safer than underground mining. Regardless of the arguments against strip mining, the energy crisis is sure to increase the pressure for more of it—at least in the near future.

Is subsurface mining safer?

This is because removing the terrain surface, or overburden, to access the mineral beneath is often more cost-effective than gouging tunnels and subterranean shafts to access minerals underground. This method is often considered safer, as well, and doesn’t require extensive electricity rigging and water piping.

Is surface mining better than subsurface mining?

Surface mining is often preferred to subsurface mining by companies in the industry because it is less expensive, there are fewer complications with electricity and water, and it is safer. However, surface mining can be more environmentally-damaging than subsurface mining.

What are the pros and cons of underground mining?

Advantages of underground mining: *less surface disturbance. *less environmental disturbance. *less waste mined per tonne of ore. *ability to mine resources that are not economic as a surface mine.

What are the advantages and disadvantages of surface mining?

This type of mining occurs primarily on mountaintops, and dates back to the early 20th century when new machines made moving earth easier. Supporters of surface mining contend it promotes clean energy, producing less environmental disturbance than pit mining. However, opponents of surface mining cite many issues with its operations.

What’s the difference between surface and underground mining?

Underground Mining. Main Difference. In surface mining, the ore is accessed directly from the Earth’s surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface.

What are the advantages and disadvantages of coal mining?

The financial and economic benefits that it provides to communities involved in the activity of coal mining. More safe as opposed to pit mining. Usage of large-scale mining equipment making the work more efficient and easy. Polluting the streams by releasing potentially harmful toxins.

• the community can earn income as they can sell the mines to other countries and areas where they are needed and earns income from that.
• there is a lot of pollution that occurs with it making the environment to be contaminated hence not healthy for animals and plants.
• Summary.

  What are the disadvantages of strip mining?

  Strip Mining Cons to Consider. 1. It requires an investment gamble. The processes of strip mining are cheaper. The actual investment into those processes, however, are typically higher than in other forms of mining. From equipment to staffing to distribution, it may not always be possible to gain an exit out of this investment.
