What is the expression for air pressure below Earth''s surface?

If you were to drill a hole in the ground, what is the expression for the air pressure below ground? Above ground it is exponential with distance (at least to an approximation), so

science based

The total mass of the moon''s "atmosphere" is something like 10t, that just isn''t enough mass of atmosphere to fill a hole. Instead you would need to use a cap to hold down

What is DTH Drilling? | Furukawa FRD

DTH drilling offers several advantages over top-hammer drilling for larger, deeper holes in medium-hard formations. Because the hammer is at the bottom of the
