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.
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.
Types of mines?

What is Underground Mining?
underground mining is done when the rocks, minerals of gemstones are too far underground to get out with surface mining some kinds of underground mining are Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining
How are diamonds mined?
The diamonds are mined by digging the earth. Sometimes the very big open pits are left after the diamond exploration. Some diamonds are found on top of the earth, having been tumbled downstream from volcanic pipes by flowing water. These are known as alluvial diamonds, and are mined by hand -- workers sifting through the bottoms of riverbeds using sieves and water to separate the raw diamonds from other material. Alluvial diamonds may also be found in ocean water at the mouths of rivers.

What are some early gold mining methods?
panning,shaft mining,cradling and puddling
How were rubies mined?
Rubies have historically been mined using traditional methods such as panning in rivers, open-pit mining, and underground mining. In some locations, rubies are also recovered by washing and sorting through alluvial deposits. Modern techniques incorporate machinery and technology to extract rubies more efficiently while minimizing environmental impact.
Where does gold exist?
Gold is found in the Earth's crust, primarily in quartz veins and alluvial deposits. It is often extracted through mining techniques such as open-pit mining, underground mining, and placer mining. Gold can also be found in small quantities in seawater and some meteorites.
When did diamond mining start?
Diamond mining started in India around the 4th century BC. However, modern industrial diamond mining began in the late 19th century in South Africa after the discovery of diamond deposits in the region.
What invention did Herbert Hoover invent?
He was a very successful mining engineer. He may have invented some new methods for handling mining difficulties. (He did not invent the Hoover vacuum.)

Do Trinidad mine for gold and diamonds?
Yes, Trinidad does have mining activities for gold and diamonds, although they are not as extensive as in some other countries. Gold mining occurs mainly in the interior regions, where small-scale operations extract gold from riverbeds and alluvial deposits. Diamond mining is less prominent, but there are known deposits. Overall, these activities contribute to the country's mineral sector but are not the primary focus of its economy.
