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.

LaoUnderground mining is a method of extracting minerals and ores that are buried deep beneath the Earth's surface. Miners create tunnels and shafts to access these deposits and use machinery and equipment to extract the valuable materials. This method of mining is often used for resources like coal, gold, and copper.

What are the different kinds of mining?
The three types of mining -strip mining,open pit mining,and shaft mining
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?
The two main types of mining are surface mining and underground mining. Surface mining involves removing minerals near the surface of the earth through open-pit mining, strip mining, or mountaintop removal. Underground mining involves extracting minerals from beneath the earth's surface using tunnels and shafts. Underground mining is generally more expensive and dangerous than surface mining.
What are the four different types of mining?
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.
