What are some advantages of subsurface mining compared to surface mining?
Subsurface mining offers more employment opportunities than surface mining would for the same volume of coal. Subsurface mining has less impact on the surrounding landscape than surface mining.. Coal companies have lower payroll costs because they need fewer miners. Mountaintop removal is less dangerous for miners.
What are the cons of subsurface mining?
Subsurface mining operations don't create the visible changes in the landscape that surface mining operations do, but the conditions of subsurface mines are extremely hazardous for the working miners. The potential for accidental cave-ins, explosions, and fires is high.
Which is better subsurface mining or surface 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.
Why would we use subsurface mining instead of surface mining?
Subsurface mining is actually less disruptive to the earth and produces less waste than surface mining, but it's also much less effective and more dangerous. Many workers die in mine collapses, which then also leaves behind a large hole from caving in of the ground above.
What is subsurface mining pros and cons?
Advantages : Safer than surface mining, faster than 60% of other mining in the U.S, less disruptive to the environment, leads to more minerals. Disadvantages : Costs more, harder to do than surface mining, takes a lot of time.
What are the advantages and disadvantages of surface mining over underground mine?
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 subsurface mining?
Definition: Mining beneath the surface of the earth.
How is subsurface mining better for the environment?
Advantages : Safer than surface mining, faster than 60% of other mining in the U.S, less disruptive to the environment, leads to more minerals.
Why is subsurface mining more expensive?
Underground mining is more expensive because it's more capital intensive. Coal companies such as Arch Coal (ACI) and Alpha Natural Resource (ANR) have to drill more and use more expensive and complicated machines.
What are the advantages and disadvantages of surface mining?
The pros of surface mining are that it has a lower financial cost and is a lot safer than underground mining because all mining operations take place above the surface. The cons are the hazards it presents to human health and the environment.
What is subsurface mining examples?
Other techniques for the mining of subsurface resources are also available. The removal of oil and natural gas by drilling into Earth's surface are well-known examples. Certain water-soluble minerals can be removed by dissolving them with hot water that is piped into the ground under pressure.
What are the pros and cons of surface mining?
The pros of surface mining are that it has a lower financial cost and is a lot safer than underground mining because all mining operations take place above the surface. The cons are the hazards it presents to human health and the environment.
What are advantages and disadvantages of subsurface mining techniques?
Advantages and Disadvantages Advantages : Safer than surface mining, faster than 60% of other mining in the U.S, less disruptive to the environment, leads to more minerals. Disadvantages : Costs more, harder to do than surface mining, takes a lot of time.
