Rimworld Mining Roof

If it s an overhead mountain collapsing colonists will be buried alive.

Rimworld mining roof.

Roof collapses cause injuries to colonists and damage items. A roof collapses if there s no support rock wall within 6 squares of the tile. So this took out 4 people. You didn t mine out a mountain you mined out a hill.

What can i do about this. For example plasteel yields 7 units per cycle making it effectively 5 times slower to mine than steel which yields 35. So i then took some guys and mined the collapsed roof at which point they each died as they finished their square. You can avoid a collapse by either not mining the whole thing or building a wall to support it.

For some reason the regular rock areas collapsed as i was mining them. Drawing a remove roof zone will cause colonists to remove a. So i try to remove the mountain roofs so they don t collapse by declareing a no roof area but on some tiles it will never be possible to declare that area and if i let the roof collapse and remove the debris it just collapses again presumably forever since i tried removing it 15 times and it still collapsed. Although this time is the same for all materials the amount per cycle varies.

Each extraction cycle takes a base of 14 000 ticks 3 89 mins of work to finish modified according to the colonist s mining speed stat. Use the planning tool to mark out your planning mining and add in the support columns based on the size of the hole you ll be leaving. Any square 9 x 9 or bigger should have 1 support right in the middle. This means that the largest square room you can have is 10x10 internal.
