Underground mining (as compared to open pit exploitation) allows a mine operation to be largely 'hidden' having only adits or headframes protruding above the surface. This enables the land above the zone of mining to be reclaimed for other uses, after the mining has ceased, so much easier than in the case of an open pit.
Underground mining can mine as deep as the development permits excavation to take place. If there is a shaft with headgear, then mining can take place until that depth. If it is accessed by horizontal adits, it can mine until the lowest adit upwards. If it is accessed by decline, the development and mining can continue so long as economic exploitation is possible. Unlike an open pit, it is NOT dependant on stripping ratios which means that deep mining of narrow geological structures becomes practical ONLY by use of underground mining.
The opportunity to use old mined out stopes as a repository for waste rock blasted in order access further, new stopes. Such a process is known as 'backfilling' old workings and helps stabilise the ground, reduces the cost of haulage and helps avoid falls of ground / rockbursts.

What is some mining equipment for shaft mining?
Shaft mining is the earnest form of underground mining. Underground mining is selected when the rock or mineral is so far to reach using surface mining. Shaft mining is the kind of mine that you normally see in movies where the miner travels straight down into a profound, dark tunnel until he reaches the base. The shaft mine has a vertical man shaft, a tunnel where the men travel up and down in an elevator. Equipment is taken into the mine using this shaft, too. Short tunnels to the ore are dug from that man shaft. When the ore is dynamited and broken into chunks, it is taken to the top and loaded into trucks through a second shaft. There is usually an air shaft that gives the mine ventilation. When we visited a coal mine, it was amazing how much air moved around in the tunnels. Moving air removes the gases that occur naturally underground.
