Columns hold up the mine's ceiling to prevent cave-ins. Stone columns have a slightly larger radius (11 tiles) than Mine Supports (9 tiles) and are generally more convenient to build in a mine due to being built with stones.
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.

Quoted from Loftar
<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 a 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

Support Radius

The squares around the column that are safe to mine.

All tiles marked in blue are safe to mine. Mining a tile outside of the blue area may cause a cave-in. This structure will support mining within a 11 tile radius.

  • Stone Columns can be built on the surface and in houses too for aesthetics.
