What are the advantages of underground mining?
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining
How do silicate minerals form?
Most silicate minerals are formed when molten rock cools at either the earths surface, or deep underground.
What is undergroumd mining?
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.

No. Granite cools from magma deep underground. Volcanic glass cools quickly at or near the surface.
Is surface mining is less coast and inexpensive?
Surface mining is MUCH less expensive than underground mining. Usually. In some cases, underground mining is used because the substance being mined is just too deep to have a surface mine. I was just in a silver mine that is more than 5,000 feet deep. If the mine had to remove a mile of rock to get to the silver, it would not be worth mining. In THAT case, underground mining is less costly.
