Monumental Columns are mining support structures which prevent cave-ins in a thirty tile radius. Monumental Columns are the last tier of Mining support/columns, below Stone Columns:
- Mine Support: 9 Tile Radius
- Stone Column: 11 Tile Radius
- Mine Beam: 13 Tile Radius
- Monumental Column: 30 Tile Radius

Note: Mined tiles will still show dust animation (see Mining page) when under the radius of the support, to warn of cave-in tiles, but caveins won't occur under support.
Monumental Column takes damage every time it prevents a cave-in. If not taken care of, this can eventually result in destruction of the Monumental Column which triggers a massive cave-in.
For a mine support structure to prevent a cave-in, it must touch the center of the tile:
| <SuperDaddy> Does it count if the radius is touching part of the tile? <loftar> Well, to be precise, it needs to touch the exact center of the tile. |
This means tiles covered by the column radius just slightly aren't supported.
Caution: whenever any mine support is removed, all tiles under it are checked for unstable mine tiles. If there are unstable tiles within range, which are now, with the removal of the mine support, unsupported, the removal will cause a cave in. This means that you can now tear down mine supports without cave ins, if you still have proper support around it

- Coq au Arch (2026-04-23)◎ >"Character should no longer stop auto-mining when not planning to mine out unsupported tiles. Notable that the character would sometimes stop for no reason when excavating tunnels."
- Monumental Tunnel (2026-03-27)◎ >"Reworked mine supports to handle more arbitrary support definitions."
- Monumental Tunnel (2026-03-27)◎ >"Added "Monumental Column", a pretty massive mine support. Suggested here!."
