Testing, or Digging a 50-mile hole

Elsewhere someone asked about making a really deep hole, maybe 50 miles iirc, with minimal magic use.

My comment:

I was thinking of liquifying the earth/stone. Or Rock to Mud and then Create Water or a Decanter of Endless Water to flush it up. Or find underground water and make a horizontal shaft to bring it in. Or run down some sort of tube from above and bring in some water from there. Or bring down some wind to blow it up, Bag of Winds or something like that.

Or get the mud out some other way. Some sort of teleport or magic item down at the bottom so they could drain down. Find caverns nearby and make drain shafts to them.

Hm, or transmute the dirt it to something edible, or valuable to some monster.

Hey, turn all the dirt into Earth Golems, one by one, and tell them to leave. "Will the Golem pls roll Dex to climb out." In a big campaign with several different groups of players, you could have a whole nother adventure start nearby with a village requesting help because they're being trampled by an endless series of golems.

Ah what a wonderful opportunity (for the DM, anyway) ... let's see, they're going to remove a column of earth (rock, etc) fifty miles deep?

Considerations:

What is the air pressure at a depth of 50 miles.

How strong are all of the strata the shaft intersects?

What about dwarf mining operations (cf Terry Pratchett's Disk World series)

Are they at all aware of the increase in temperature with depth? Existing mines (much shallower) become very warm at much lesser depths.

What if they strike a magma pocket?

Oh, fabjurous joy! The DM's heart sings at the thought! Surely there are elder gods -- and powerful elementals -- who would smile happily at the attempt ... and might well seek to encourage success.

The DM said (more or less) that this wasn’t Kansas and everything was different, and his world didn't have those problems re temperature, pressure, etc. He just wanted ideas for what low or moderate level magics or other moderate level stuff could be used to make such a tunnel.

I had the impression that he had sort of turned our solar system inside out. We have little balls of dirt enclosed in endless space, he has endless dirt with little round bubbles in it. Etc. So this project might be like our space program, trying to get to adjacent worlds, except where we build rockets and fly, they have to dig tunnels.

He said gravity gets less as you go further from a bubble, and when you get to the half way point it ‘flips’. So I guess from either end, gravity is pulling toward the middle, though weaker the closer you get to the middle.
