What is deep lead mining?
Deep lead mining is a form of underground mining. Deep leads are old riverbeds that have become buried.
What type of rock can only form deep underground?
Metamorphic
Granite is an example It forms deep underground It needs heat to form What is it?
It is metamorphic rock
How do silicate minerals form?
Most silicate minerals are formed when molten rock cools at either the earths surface, or deep underground.
How do solutions of water elements and compounds that can crystallize into a mineral form deep underground?
Over time, minerals are created by elements bonding together to form other solutions. Since they are underground, there is nothing disrupts the process, which gives nature enough time to let the elements bond.

What is the difference between open-pit mining and underground mining?
I was searching for an answer for my science homework, when I stumbled upon this answer. This was very incorrect, and I would like to fix it for you. Here is the correct answer: Open Pit Mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.Hope this helps!-Jane Derdoy
What two things make possible sedimentary and metamorphic rocks to form deep underground?
Heat and/or pressure.
How do silicate minerals form?
Most silicate minerals are formed when molten rock cools at either the earths surface, or deep underground.
Is it dangerous mining gold?
Mining is potentially a very dangerous occupation, however, with the health and safety rules in place in most Western countries these risks are well managed. Firstly, are you talking about open cut or underground mining? Depending on the nature of the gold deposit this will dictate the mining method used to extract it. This may range from large open cut operations to small narrow vein airleg mining which is performed underground. Obviously, underground is potentially a more dangerous environment due to the potential for rock falls, equipment fires and even gas explosions (in some mines, not all). Compared to coal however, many consider hard rock mining (ie: gold, nickel, zinc, copper etc) to be far safer due to the fact that metal deposits tend to form in hard rock environments, whereas coal is a sedimentary deposit and is softer. This means that coal mines have a higher potential for roof (or 'back' as we say in metal mining) failure. Actually, in longwall mining for coal the roof is designed to collapse behind the mining front. Underground workings are supported with steel bolts and mesh to prevent them caving which is crucial to stability underground. So generally, wherever you are underground the risk of rock fall is minimal...as long as you NEVER walk under unsupported ground...a BIG NO NO IF YOU WANT TO LIVE. Before you work underground you will receive induction training and what to do in case of emergencies etc. It may seem scary at first but it is very exciting working underground, and the guys on your crew will look out for you as a new guy. That's what is so cool about mining, there is a lot of camaraderie on the mines, a great working environment. So, basically, there are obvious risks in mining especially when you have such large machinery in enclosed spaces, explosives to play with, blasting hauling etc etc. But with some decent initial training, working safely and looking out for your crew mates there is no reason why mining should be any more dangerous in reality than other professions. Comments are based on my experience as a miner/mining engineer working in underground nickel, gold and coal mines
Where does the change of an igneous rock occur?
Igneous rock may either form on or near a volcano or deep underground where magma has intruded into the crust.
