40d:Mineshaft stitching

When using mine shafts, dwarves will prefer to dig all of one level before moving on to the next. This can result in a lot of time spent moving, as miners go up and down mine shafts. If you have a large number of relatively unskilled miners, this is unlikely to be a problem: digging time will dominate in any case. If you have one or two legendary miners, this is quite annoying. As a solution, you can creating a single path that forces your dwarf to finish one shaft before moving on to the next. To do so, connect shafts alternately at the top and bottom layers, so the shaft snakes through the area. For example, the top, middle, and bottom layers could look like:

▒▒▒▒▒▒▒▒▒
.X▒▒X..X▒
▒▒▒▒▒▒▒▒▒
▒▒▒▒▒▒▒▒▒
▒X..X▒▒X▒
▒▒▒▒▒▒▒▒▒

▒▒▒▒▒▒▒▒▒
▒X▒▒X▒▒X▒
▒▒▒▒▒▒▒▒▒
▒▒▒▒▒▒▒▒▒
▒X▒▒X▒▒X▒
▒▒▒▒▒▒▒▒▒

▒▒▒▒▒▒▒▒▒
▒X▒▒X▒▒X▒
▒.▒▒.▒▒.▒
▒.▒▒.▒▒.▒
▒X▒▒X▒▒X▒
▒▒▒▒▒▒▒▒▒

Note that this pattern creates a very long walkway back to the start of the mineshafts. If you do not excavate routinely, consider connecting the top-level paths of areas you have already explored.

AKH script

An AKH script to construct such a pattern is provided below, based on this script, but using many fewer keystrokes.
