Most deep mines are very warm. The two big sources of heat in mines are the rock (warmed by heat from deeper), which heats up the air, and autocompression.
Groundwater, etc, can affect the temp of shallow mines, but below a few hundred feet, it's pretty much that deeper = warmer. There are very few mines "near" magma sources, though some areas of the crust are warmer than others. Also, nearby water flows can affect the temperature. Deep mines are almost uniformly warm to hot, though.
The second source of heat is the compression of the air sent into the mines. Since the mine is so deep, the column of air is heavier, increasing the air pressure inside the mine. This increases the temperature of the air as well.
Finally, almost all of the energy from drilling, blasting, machinery, etc, ends up in the rock, warming it.
