The type of mine is called a strip mine.
Shaft mining.
This type of mining is called underground mining. Miners access the ore through tunnels and shafts dug beneath the surface of the Earth. It is often used when the ore deposits are located deep underground.
Igneous rocks such as granite and basalt are commonly found deep underground as they form from the cooling and solidification of magma beneath the Earth's surface. Metamorphic rocks like gneiss and slate can also be found deep underground as they are formed from the alteration of existing rocks under high temperature and pressure conditions.
It can be both. Right now, the largest gold mine in Australia is an open pit mine. However, The Homestake mine in South Dakota was 8000 ft deep- an underground mine with 375 miles of passageways. It all depends on where the gold is located.
If you dug a hole 592 kilometers deep, you would reach the upper part of the Earth's mantle, which extends from the crust to about 2,900 kilometers beneath the surface. You would not reach the Earth's outer core, which starts at a depth of about 2,900 kilometers.

Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
Ocean currents is what forms surface currents. This starts deep in the ocean.
channel perhaps?
Shaft mining.
Rivers' surface located in deep valleys can be below of the ocean surface. Furthermore, there are underground rivers which certainly are below sea level, depending on how deep such rivers are placed below-ground.
All earthquakes occur underground, the exact place where the earthquake starts underground is called the Focus. The location where the earthquake first hits the surface of the earth is called the Epicenter! Hope I helped!
Springs: This is groundwater that emerges at the surface from deep underground. Immense pressure combined with the structure of the local geology forces the water to the surface.
