Summary0008667: Miners climb out of vertical chutes while digging, refuse to continue
DescriptionI'm trying to dig a drop chute through ~ 130 Z levels using the regular technique (channel straight down) but it's proving to be difficult in these recent versions.

First, if I just channel down then at some point the miner gets "bored" and climbs back out of the hole. This happens fairly quickly, like after only digging down 5 levels. Once he climbs, the bottom of the hole becomes off limits for future miners. In other words he can climb up but will never climb back down.

To avoid this I tried sealing off the top of the hole with a door, to help him focus on his job. Eventually though I get an announcement "Urist cancels Dig Channel: Dangerous terrain" and he stops mining. What has occured is that he is now stuck 1 level above the bottom of the hole. Either he has grabbed onto the wall to avoid falling, or he climbed back up after falling. He then refuses to mine any more and needs to be extracted (I can do this by unsealing the hole -- he then climbs back out.

The workaround for this, I suppose, is to dig some stairs adjacent to the chute.

 Huh, I had actually posted a queston on the FotF (Future of the Fort) thread in relation to this.

Have you tried doing a vertical series of ramps, that might work. Another alternative is to dig a shaft with up/down stairs and then channel out the stairs, which they should be able to do from below.

Edit: Also, a save of this in progress would be great.

 Has anyone seen this occur in versions prior to 0.40.20? I'm fairly certain I used this strategy in 0.40.19, and it doesn't appear to work in 0.40.23 (even when no other areas are designated for mining).

 Well, logically, if it wasn't, people would have complained/asked about it or made bug reports if it happened before 40.20.

 Well I can confirm that designating a tall up/down staircase adjacent to the channels results in a clean dig. No miners were injured even though multiple miners were involved. I did set a higher priority (lower priority number) on the staircase, if that matters.

I am not sure if channeling out the staircase itself would work, at least, I don't feel like designating one by one and if I designate the whole staircase simultaneously, the miners would probably end up falling. Haven't tried it though, anybody have experience with this technique?

Probably we'll just have to live with miners trying to avoid falls when they channel under themselves.
