How does strip mining differ from the traditional practice of tunneling into the mountain?
Strip mining involves removing the surface layer of soil to access mineral deposits, while tunneling involves creating underground passages within the mountain to reach the minerals. Strip mining causes more visible environmental impact due to the removal of topsoil, vegetation, and altering the landscape, whereas tunneling has less surface disruption but can lead to issues such as subsidence and groundwater contamination.
Strip mining is less harmful to the environment than shaft mining but more dangerous to miners?
Strip mining involves removing soil and rock to access mineral deposits, causing extensive habitat destruction and soil erosion. It can have significant impacts on the environment, including loss of biodiversity and water pollution. However, compared to shaft mining, it poses fewer risks to miners in terms of accidents and exposure to hazardous conditions underground.
What mining technique is less harmful to the environment surface or subsurface mining?
Subsurface mining is generally considered less harmful to the environment compared to surface mining. Subsurface mining causes less land disturbance and produces less waste material on the surface. However, both mining techniques can have environmental impacts if not properly managed.
What type of mining is least harmful to the environment?
Underground mining is generally considered less harmful to the environment compared to surface mining. Underground mining causes less surface disturbance, reduces the impact on wildlife and ecosystems, and generates less waste compared to surface mining methods such as open-pit mining.
What are some of the advantages and disadvantages of subsurface mining techniques?
Advantages of subsurface mining techniques include access to valuable minerals located deep underground and the ability to extract resources that are not easily accessible through surface mining. Disadvantages include environmental impacts such as habitat destruction and water pollution, as well as safety risks for miners due to working in confined spaces and potential for accidents.
How do surface mining and underground mining differ?
Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
Is there solutions of less coltan mining?
yes
Is surface mining is less coast and inexpensive?
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.
What are two types of coal mining?
Surface mining is used to produce most of the coal because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.In surface mining, giant machines remove the top soil and layers of rock known as "overburden" to expose the coal seam. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.Underground mining, sometimes called deep mining, is used when the coal is buried several hundred feet below the surface. Some underground mines are 1,000 feet deep. To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal.
What are the two main types of mining and how do they differ?
The two main types of mining are surface mining and underground mining. Surface mining involves extracting minerals or resources from the Earth's surface, while underground mining involves extracting resources from beneath the Earth's surface. Surface mining is generally more cost-effective and less dangerous, but it can have a larger environmental impact compared to underground mining. Underground mining, on the other hand, can be more expensive and pose greater safety risks, but it is less disruptive to the environment.
Was crime more of a problem today or in the roman era?
Crime is more of a problem today because in roman times it was punishable by death so less people commited any crimes,where as today people dont realy care if they commit a crime because they know they will get away with it.
What are the benefits of surface mining over subsurface mining?
Surface mining is generally more cost-effective and less dangerous than subsurface mining. It also has a lower environmental impact as it causes less disturbance to the surrounding ecosystems. Additionally, surface mining allows for easier access to the mineral resources, making it more efficient.
