Although today mining is generally associated with obtaining metals or coal, the earliest mines were focused on obtaining ore that could be used as dyes (hematite) or for tool construction (flint).
The oldest known mine is the "Lion Cave" in Swaziland. It dates back 43,000 years. At the same period early man was mining flint in Hungary.

What are the different kinds of mining?
The three types of mining -strip mining,open pit mining,and shaft mining
How is ore extracted from the ground?
The general term we apply to ore extraction from the earth is mining, and mining technology or mining engineering are the disciplines under which mining is practiced. Need a link? You'll find one below to the Wikipedia post on mining. If your question is applied to the mechanics of mining, we have to locate and map deposits of mineral ores. Then sample and test them for concentration ("richness"). Then either dig a shaft or start removal of overburden to form a pit. We can drill to set charges, blast, and then send in men and equipment to remove the material and get it out to a place from which it can be routed to processing, either on site or at a remote location.
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 forms of subsurface mining?
Forms of subsurface mining include drift mining, slope mining, shaft mining, and room and pillar mining. These methods involve accessing minerals or resources beneath the Earth's surface through tunnels, shafts, or other underground workings.
What are two main types of mining and how do they differ?
What are two main types of mining and how do they differ? Open cast mining, and underground mining. The reason they differ, is because underground mining is where they create shafts that lead to ore beds. Open cast mining, is the opposite of underground mining. I really hope this answer is useful! I love to help people get better at science. I hope I helped you guys! Bye.

Describe 2 ways to reduce the effects of mining?

What is the best paying career between mining enginering and geology?
A mining engineer will earn around 93,000 dollars a year. A geologist will earn around 73,000 dollars a year. A mining engineer earns quite a bit more money than a geologist.
How much does a mining engineer earn?
depends on what you mine and how successful you are, but generally speaking, a mining engineer can make between 60 and 200k a year
What year did year mining start in Australia?
Mining prior to the arrival of the Europeans cannot be defined by a date. For thousands of years, the Aborigines had already been mining ochre (used in art and for ceremonial purposes) and stone. They established quarries and transportation routes for trading between tribes. In regards to European settlement, mining started following the discovery of coal in the Newcastle area. Originally discovered by excaped convict William Bryant in 1791, it was not reported until an English officer found a coal seam, in 1797, whilst searching for escaped convicts. Coal was mined and exported, beginning in 1799. The first coal mining settlement was established at Newcastle in 1801.

Which gold mining companies will soon start producing gold?
Several in Sierra Madre, in Mexico
When did coal mining start in US?
Around 1730 in Virginia. See the related link below on history of coal mining. As well, consider American Indian use of coal long before settlements in the Americas. 1730 is an excellent answer regarding industrial U.S. coal mining.
How do you get plate Pokemon diamond?
