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
Deep lead mining is a form of underground mining. Deep leads are old riverbeds that have become buried.
Deep mining of any kind is done in tunnels leading off a vertical shaft into the ground, as opposed to 'open pit' or 'strip' mining. Deep mining is principally done for copper.
that they are mint :)

'Advantages' in this case relates exactly to economics -- if the investment in a mining operation produces a profit, then the advantage is money.
