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.
How does underground mining work?
Underground mining involves digging shafts and tunnels to access mineral deposits buried deep in the ground. Miners use specialized equipment to extract the ore, which is then brought to the surface for processing. Support systems are in place to ensure the safety of miners and to prevent collapses in the underground mine workings.
Why Is Coal Found Underground?
Coal is found underground because it is formed from the remains of plants that lived in swamps millions of years ago. Over time, the plants decomposed and were buried by layers of sediment, leading to the formation of coal deposits deep underground.
Why did gold miners mine underground?
Gold miners mined underground to access deeper veins of gold that could not be easily reached through surface mining methods. Underground mining allowed miners to extract gold from deposits that were buried deep beneath the earth's surface, leading to potentially higher yields of gold.
What is deep lead mining?
Deep lead mining refers to the extraction of lead ore from deep underground mines. This process involves digging shafts and tunnels to access the lead deposits found deep within the earth. Deep lead mining can be a dangerous and challenging endeavor due to the depth and complexity of the mines.

Does and organism have to be buried to become a fossil?
No, an organism does not have to be buried to become a fossil. Fossils can form through a variety of processes, such as compression, mineral replacement, or petrification, which can occur even without burial.
Can PEX pipe be buried underground?
Yes, PEX pipe can be buried underground as it is commonly used for underground water supply lines.
Why is exploration for mining sites for extracting mineral resources like 'finding a needle in a haystack'?
Exploration for mining sites can be compared to finding a needle in a haystack because it involves searching vast areas of land for specific mineral deposits that are often invisible and buried underground. Just like searching for a needle in a haystack, it requires careful planning, advanced technology, and a bit of luck to locate economically viable mineral resources amidst a large expanse of earth.
What is deep leads?
Deep lead mining is a form of underground mining. Deep leads are old riverbeds that have become buried.
Where is Charlotte Dymond buried?
charlotte dymond is buried in a place underground.
Where is coal located?
Coal can be found underground in coal mines, usually in coal seams or coal beds. These deposits are typically found in regions with former swamps and wetlands where plant material accumulated and was eventually buried and transformed into coal over millions of years.
What is a synonyms for subterranean?
Hidden, underground, private, covert, secret, buried...
How is sulfur obtained?
Sulfur is typically obtained from natural sources such as underground deposits or volcanic regions where it occurs as elemental sulfur or sulfur-containing minerals like pyrite. It can also be recovered as a byproduct of petroleum processing and natural gas refining. The extraction process involves mining or drilling for sulfur ores, followed by purification through methods like the Frasch process or flotation.

Does something buried have to be underground or can the buried item be in a wall?
anything could be buried in a wall. In fact most Egyptian Pharaohs were buried in walls
