Surface mining and subsurface mining are both methods used to extract minerals from the Earth's crust. However, surface mining involves removing the overlying rock and soil to access the mineral resources, while subsurface mining involves digging tunnels or shafts underground to access the mineral deposits. Both methods can have environmental impacts and require careful planning and management to minimize these impacts.
What else can I help you with?
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.
When will surface mining and subsurface mining be used?
Surface mining is used when mineral deposits are close to the surface, making it more cost-effective and efficient to extract them using methods like open-pit mining. Subsurface mining is employed when mineral deposits are buried deep underground, necessitating techniques such as shaft mining or drift mining to access them. The choice between surface and subsurface mining depends on factors such as the depth and location of the mineral deposits, environmental considerations, and cost-effectiveness.
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.
Compare and contrast surface mining and subsurface mining on the basis of cost safety land disturbance and energy use?
Surface mining is generally cheaper than subsurface mining, as it involves fewer machinery and labor costs. However, surface mining can cause more land disturbance and environmental damage due to the removal of topsoil and vegetation. Subsurface mining, while more expensive, is often considered safer as mining activities are conducted underground. Both methods require significant energy use, but subsurface mining may consume more energy for ventilation and transportation.
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.

What are types of minning?
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
What types of minnings are there?
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
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 kind of surface or subsurface mining was done in Leadville Colorado?
In Leadville, Colorado, both surface and subsurface mining were conducted. Surface mining involved open pit mining for materials like gold and silver. Subsurface mining involved digging shafts and tunnels deep underground to extract minerals like lead and zinc.
Is iron mined using surface or subsurface mining?
Yes

What are surface and subsurface mining techniques. what are some of the advantages and disadvantages of each technique?
Surface mining involves extracting minerals near the surface by removing vegetation and soil, while subsurface mining involves digging tunnels deep underground to extract minerals. Surface mining is faster, cheaper, and less hazardous to miners but can lead to environmental degradation and habitat destruction. Subsurface mining is safer for the environment but poses higher risks to miners due to the potential for collapses and gas explosions.
What are the surface and subsurface methods by which coal is commonly mined?
Surface mining methods for coal include strip mining, open-pit mining, and mountaintop removal. Subsurface mining methods involve underground mining techniques such as room and pillar mining, longwall mining, and shaft mining. Each method has its own advantages and challenges in extracting coal from the earth.
