Mining is removing a mineral or metal from the earth to use it or sell it. When the substance being mined is close to the surface, it is simply dug out of the ground (surface mining). However, if the substance is deep underground, a shaftway may be dug to reach the material, much like a tunnel. That is underground mining.
The three types of mining -strip mining,open pit mining,and shaft mining
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.
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? 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.
The four main types of mining are surface mining, underground mining, placer mining, and in-situ mining. Surface mining involves removing soil and rock to access minerals, while underground mining involves tunnels and shafts to access deposits. Placer mining involves extracting minerals from loose deposits like sand and gravel, while in-situ mining involves extracting minerals without removing the ore body from the ground.

In the full version of Minecraft, obsidain is usually found in the deep part of caves. Since there are no cave systems in minecraft pe, it's really hard to find it. You just have to keep on mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining and mining until you luckily find obsidian.

mining the data is called data mining. Mining the text is called text mining
I OH NO
All types of mining from copper mining to gold mining to zinc mining.
The three types of mining -strip mining,open pit mining,and shaft mining
THERE ARE DIFFERENT TYPES OF MINING SUCH AS SURFACE MINING,open cast mining, strip mining,alluvial mining,quarrying mining,underground mining,and drilling
the 5 types of mining are "sub-surface mining, surface mining, open-pit mining, dredging, and strip mining" please like :)
Uranium mining can be either by open pit mining or by underground mining.
Underground mining surface mining
