Exploring Underground Mine Access Methods

Getting into an underground mine is like choosing a highway into the Earth's crust.

It's not just one big hole. For mines built into mountains, you can drive straight

in through a horizontal tunnel called an adit. For shallower deposits, they build an incline,

a sloping road perfect for conveyor belts to haul out minerals. Some mines even have spiral declines,

like a massive underground parking ramp, where huge trucks drive up and down. But for the really

deep stuff, they sink a vertical shaft—a giant, high-speed elevator for people and rock.

Each entry is a massive engineering feat.
