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.

What Is A new cryptocurrency 2022?
Pi is a new crypto currency for and by everyday people, which has been developed by Stanford graduates with the intention of making crypto currency accessible to everyday people. One just has to install the application on the mobile and start mining. Mining is free as of now. But one needs a witness code to start mining. The application doesn't drain the battery. One has to click the button only once a day to continue mining. Pi network currently has 14 million pioneers. It would launch the manner by the year end or early next year. The free mining stops once it reaches 100 million pioneers. The mining rate as of now is 0.12π/hrs. which becomes lower as the number of pioneers increase. And the more people use your witness code to start mining, the more and faster you mine.
When did mining first start?
1746 in Britain
