The density of granite is 2.7 t/m³. Just multilpying the m³ by 2.7 t/m³ will results as tonnes. Regards mockingbird.
South Africa is where it's at for deep mines. And what are they digging for? Gold! AngloGold Ashanti's Savuka mine near Carletonville is currently the world's deepest mine at just less than 3.8km below the surface. Gold Fields mines Driefontein will be the world's deepest mine at 4.1km below the surface and Kloof will be the second deepest mine at 4km underground when their extensions are complete. They're digging them now. At this stage AngloGold Mponeng mine is official the deepest mine in the world and the current project will take it another 300 meters deeper.
The Earth's core is about 7 times the density of the surface rock. That means, a person in a deep mineshaft is getting closer to more mass. Therefore, density is relative to the depth of the earth by the correlation this has on a person's weight.
Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.

The average density of granite is 2.75 g/cm3.
Kolar is the deepest gold mine in the world.
Granite chippings are granite aggregates that are primarily composed of feldspar and used as paving material. The density of granite chippings is 166.5 lbs / ft3 .
The deepest coal mine in Europe is Jindřich II Mine in the Rosice-Oslavany coal basin, Czech Republic. The shaft of the mine reached 1550 m while the deepest level coal was mined at was at 1428.4 m. The mine was closed in 1991. It is probably the deepest coal mine in the world.Springhill Mine, near Springhill, Nova Scotia, Canada, is the deepest coal mine in North America. The greatest depth of the Springhill area mines is about 1350 m. The mine was closed in 1958.
The deepest gold mine in Australia is the Super Pit or Kalgoorlie-Boulder. This mine produces 850,000 ounces of gold yearly.
Granite.
The deepest mine in Europe is located in a small city called Pyhäsalmi in Finland. The depth is 1,4 km.
The Enterprise mine, a copper ore mine located at Mt Isa Mines, is currently Australia's deepest mine. Its shaft is 1,900m deep.

Rhyolite is the extrusive equivalent in chemistry and density of granite.
