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.
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
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.
Yes
The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake. The water that goes on the top of the ground is going to the oceans. The subsurface run-off is that when it is preciptation the water
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.
Strip mining involves removing the surface layer of soil and rock to access coal, ores, or other minerals, while subsurface mining involves extracting minerals located deep underground. Strip mining is typically more destructive to the environment due to the large-scale removal of topsoil and vegetation, while subsurface mining can have environmental impacts such as groundwater contamination and subsidence.
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.
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.
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.
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.
