It is logical to assume that there are additional openings to the mine
that
replenish the air which is lost through the exits. Since it is unlikely
that 
air circulators and blowers from the old mine are still operating, the 
circulation must result from convection currents within the mine.
These could be caused by internal heating sources such as nearby
magma pools or radioactive sources in the process of decay. Is it 
possible to enter the mine and track down the origin of the heat source?
