Re: air blowing out of an old mine

Herbert H Gottlieb says:

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?

Instead of heating sources, what about the simple enormous thermal resevoir
that is the earth? What is it, about 58 F? Does the air flow possibly
reverse in winter?
