We see the application of the term mine (as in land mine) to a high explosive weapon that can be set on or beneath the ground, and which is triggered by someone stepping on it or a vehicle rolling over it.
The same name applies to a similar nautical weapon that floats at or just below the surface and is detonated when hit by (or sometimes by the proximity of) a ship.
We use the general term mining to describe the activity of recovering materials from the earth. It is from these raw materials we take minerals we need or the raw material from which we win metal. Mining is a broad term, and there is more to it than might meet the eye.
In mining, we might extract the ore of a metal. After processing, we'd win the metal, be it iron, copper, aluminum, or any other metal we use (and we use most of them!). In the case of stone for use as a building material, we mine the marble, granite, limestone, slate or any other rock we can utilize. Sand, pieces of rock and other aggregate products are also mined, and they are vital to building and construction. Even if you call the activity quarrying, you are describing a mining operation. The earthen materials necessary to make Portland cement are mined. Imagine a world without cement, if you can. There is so much more.
Clay and other earthen materials are used in the ceramics industry. Glass manufacture would be impossible without mining. And let's not forget that we also mine "rocks" like diamond, ruby, emerald and the like. Borax, mica and other minerals are extracted from the earth to be used in thousands of applications. Scouring powder has minerals in it, and they were mined. So were the minerals used to make the sheet rock (wallboard) in a home or other structure. Let's keep going.
Moreover, Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Coal is burned in massive quantities to generate electricity. It has to be mined. So does the uranium ore we use to produce the uranium we find in nuclear fuels. Mining is a broad topic, and specifics are easy to list because we utilize so many products of mining in our daily lives.
There are so many things that are mined. Some of the common minerals include iron ore, coal, gold, lead, silver, copper, limestone and so much more.
How do you minimize the harmful effects of mining?
Surface Miningeasier than subsurface miningdoes more damage to environmentcreates more of a messSubsurface Miningit is very dangerousyou retrieve minerals from undergroundyou have very little air underground
Mining usually tears up large areas of the countryside. A lot of effort goes into recovery of sites, and this costs in terms of dollars, energy and time. Mining, particularly underground mining, is a dangerous business. Many miners are killed or injured every year in accidents (particularly in China). Additionally, mining is conducted to recover ore or aggregates. Processing ore to recover metal takes energy and creates lots of opportunities for pollution. Pollution from the recovery of metal from ore is a serious issue.
Modern mining techniques are highly mechanized. Huge earthmoving equipment scoops up ore materials and places them in giant haulers to be transported to mechanized processing facilities. Computers control much of the operation from start to finish. Explosives are used to break up rock in manageable chunks for extraction. Underground mining is more labor intense due the close quarters environment, but can still be highly mechanized.

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.

The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
mining the data is called data mining. Mining the text is called text 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
I OH NO
The three types of mining -strip mining,open pit mining,and shaft mining
All types of mining from copper mining to gold mining to zinc 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.
