Gravitational physics.

If I drop something down a deep channelled-out shaft, does it fall straight down to the bottom, or would it bounce off of the sides?

Items than enter free fall with a horizontal movement will retain that horizontal movement while falling and hit the wall (assuming it's reached before the bottom is). However, I think the collision with the wall is completely unelastic, so once the wall is hit the rest of the fall is straight down (a mine cart with sufficient speed will spread its contents, while at a lower speed the contents remain inside).

Does dumping into a dump-zone generate horizontal movement?

No

One of the dwarfs walked in front of Thor to get a better view of the prye, and Thor kicked him irritably into the middle of the flames, which made Thor feel slightly better and made all the dwarfs feel much worse.

What happens if an item falls onto a slope or ramp on the way down?  My guess is that it stops there as if it hit a floor, but it's something that probably should cause deflection.

It stops when hitting a ramp, unless "it" is a minecart and there are valid tracks to roll down on the ramp.

It's a Schrodinger's ramp. It points of n whatever direction is valid for the purposes of motion. As such, in its 'uncollapsed' waveform form it is an average of all ramp orientations leading up to each of the seven potentially valid (not just current, but 'whenever') ramp-top-ends from each of the eight options of ramp-bottom-end. This results in an unbiased superposition with zero effective slope in any direction.

Tracks are Classical, but do not collapse the wave for untracked things and beings.

I was thinking of ways to keep the main/living section of my fort in a completely separate "structure" from the mine section, complete with its own surface-entrance and everything.
