Oh, dude, converting cubic meters of granite to tons is like converting apples to oranges. But hey, if you really wanna know, you can use the density of granite (around 2.7 tons per cubic meter) to do the math. Just multiply the volume in cubic meters by the density to get the weight in tons. Easy peasy, right?
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.
Iron has the greatest density, followed by granite, water, and then dry air. Density is the mass per unit volume of a substance, and iron has a higher mass per unit volume compared to granite, water, and dry air.
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.
The deepest gold mine in Australia is the Super Pit or Kalgoorlie-Boulder. This mine produces 850,000 ounces of gold yearly.
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 mine in Europe is located in a small city called Pyhäsalmi in Finland. The depth is 1,4 km.
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 Enterprise mine, a copper ore mine located at Mt Isa Mines, is currently Australia's deepest mine. Its shaft is 1,900m deep.

A mine in Mirny, Siberia claims online to be the largest, deepest diamond mine, to a depth of more than 500 meters. You can read more about it, and view images, below.

20 grams of granite has more density compared to cotton balls because granite is denser and heavier than cotton balls, which are lightweight and fluffy. Density is defined as the mass of an object divided by its volume, so even though both may weigh the same, the volume of granite is smaller, resulting in higher density.
Why do you want to get in the mine? actually the mine isn't mine and the question also isn't mine it's your's you answer it! :D
