The giant drill used to tunnel through mountains is called a tunnel boring machine, or sometimes just a boring machine. These machines can cut through both soil and rock.

A rock drill is used in various surface drilling and mining operations and can usually be found on construction sites or quarries. Specific uses of a rock drill include digging wells, penetrating rock, and creating tunnels.
A rock drill may be tipped with industrial diamonds, because the diamond tip makes the drill harder than the rock(s). Diamond is the hardest natural mineral on Earth.
You have to drill to the Aquifer
Depends on the type of mine. For surface mining, we use a track drill. This is a mobile piece of equipment, mounted on tracks. A "top hole" drill uses drill steel (hardened steel rods) that are hammered into the rock, and rotate, crushing rock to powder, which is blown out by water or compressed air. Some drills use rotating bits that grind their way through the rock. Underground mining may use a "Jumbo", which has several drill bits mounted on one machine, or a "jack leg" drill- a hydraulic jack braces the drill against to roof and floor, and hammers a bit into the rock. In a few special mines, a thermal lance is used to burn holes into the rock. PS- good drilling= good blasting= good mining.
