Abandoned cave removal

There's a cave (with chest and furnace) in my new zone, next to my mansion.
It's right under the surface and probably left since weeks.
I cant build a flat way around the mansion without breaking the cave.
So im asking for a removal of this cave.

Coords: (-469.2798, 67.0000, 520.7775) ..it's 2-3 blocks below..


Also i'd be happy if these 2 lil things can be moved:

- private door (-472.8804, 67.0000, 472.8643)
- private door + chest (-492.4861, 69.0000, 540.2424)

Both are located on grass, where there is nothing else.
They have no use, they're just in the way.

Thanks!
