Some surface mining methods include open-pit mining, strip mining, mountaintop removal mining, and placer mining. These methods involve removing the overlying material to access the desired mineral deposits near the surface. Surface mining is often used for coal, metals, and other minerals that are located close to the Earth's surface.

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.
What are the two methods used for mining coal?
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
What are the methods of mining?
There are a lot of different divisions. In general, you might separate them into surface mining, such as a quarry, strip mine, or open pit mine, and underground mining, consisting of shafts and adits.
What type of mining can i use with an horizontal layer of coal close to the surface?
You can use surface mining methods such as open-pit mining and strip mining for a horizontal layer of coal close to the surface. These methods involve removing overburden to access the coal seam, making them suitable for shallow coal deposits.
What are the advantages of underground mining?
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining

Quarrying and solar evaporation are included in which type of mining?
Both quarrying and solar evaporation are included in the category of surface mining. Surface mining methods involve removing minerals or other materials from the Earth's surface, as opposed to underground mining where resources are extracted from beneath the ground.
What are the advantages of underground mining?
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining
Why are open pit mining and strip mining both considered to be surface mining.?
Because - the mining company simply 'strips' off the surface layer of soil to get at the layer of ore underneath.
What are different types of surface mining?
Types of surface mining include open-pit mining, quarrying, strip mining, and mountaintop removal mining. These methods involve removing overlying vegetation, soil, and rock to access ore or minerals near the surface. Each type of mining has various environmental impacts that should be considered.
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 kind of mining would early prospectors use to extract shallow deposits of ore?
Early prospectors would use surface mining methods such as panning, placer mining, or open-pit mining to extract shallow deposits of ore. These methods involve manually removing the ore from the surface or near-surface layers of the earth without the need for extensive digging or tunneling.
How is surface mining similar to subsurface mining?
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 are the different methods of mining?
Here are two of the main categories of mining:Underground Mining - Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined. Shaft mines are the deepest mines; a vertical shaft with an elevator is made from the surface down to the coal.Surface Mining - Surface-mining methods include area, contour, mountaintop removal, and auger mining. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. Huge dragline shovels commonly remove rocks overlying the coal (called overburden).
