Well, you are lower, there is more "head" above you, more air piled directly above you. Same thing as going deep in the ocean, except you are going deep in air, so the pressure does not go up as fast as if it was water, but it WILL go up.

Same reason why air pressure increases when coming in from outer space. There's more air pressing on top of lower levels. Think of a tube extending from the bottom of the mine up all the way into outer space. The lowest part of the tube has got more air mass over it, so the pressure is the highest.

Air pressure depends on how much air is ABOVE you. If you climb a Mtn the air pressure goes down. If you go deeper than the surface of the earth, the pressure goes UP.
Same with water pressure in the ocean, the deeper you go, the more the pressure is.
Link in the source box below is more than you ever wanted to know.

You experience more gravitational force from the earth because you are closer to its center of mass. Atmospheric pressure is partially dependent on the gravitational pull at that location. Also there is more air above you pushing downward.

atmospheric preasure. The air above the air you breath pressing down on itself. in a deep cave you do not have air on top of air pressing down so air preasure is lowered.
hope this helps
