Yes, when they do this it is called surface mining.
smelting
There were 700 miners The population is 30,000
In some cases, the toxic gases can KILL the miners. Also, the coal can give the miners lung cancer; like smoking. Research a bit more on miners, if I were you.
On the surface no nuclear explosion no matter the yield could do it, the atmosphere provides insufficient tamping for this and would simply be blown away into space above ground zero. To get enough tamping, the explosion would have to be very deep subsurface, probably hundreds of miles or more into the mantle. We can't drill a hole that deep.

You got me... Hi, I found a link where u can try. http://seekitnow.info/314667/tamping-machine
Chile that's why there are called the Chillian miners

Miners.
Copper as a metal is mined from copper nodes by miners; in order to buy it, you'd have to check the Auction House, where the miners then sell their copper. Copper can be sold as either ore, or as copper bars.
Tamp means...To pack down tightly by a succession of blows or taps.To pack clay, sand, or dirt into (a drill hole) above an explosive.Phineas Gage used a tamping iron. He drilled holes in rocks and metals. Obviously that's where the "tamping" iron got its name!
