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 mining methods did the Chinese use at the gold rush?
things like flowers and unacotti
What are the three gold mining methods?

Which type of mining would be use to extract a vein of ore from deep underground?
Shaft 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.
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 that people use to extract coal?
Open cast and mining are the 2 used
What are some surface mining methods?
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.
How is coal obtained?
Coal is obtained through mining. It is typically extracted from underground mines using various methods such as longwall mining or room and pillar mining. Once the coal is extracted, it is processed and prepared for use as a source of energy.
