Rimworld Mining Roof

Any square 9 x 9 or bigger should have 1 support right in the middle.

Rimworld mining roof. What can i do about this. Although this time is the same for all materials the amount per cycle varies. A roof collapses if there s no support rock wall within 6 squares of the tile. A roof will collapse if the last supporting wall or rock is removed whether by mining deconstruction or destruction.

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. When i say add in i meant not dig that area though you can add in the supports stone or metal before the hole reaches critical size. For example plasteel yields 7 units per cycle making it effectively 5 times slower to mine than steel which yields 35. If it s an overhead mountain collapsing colonists will be buried alive.

So if you mine a roof that has already collapsed it re collapses and kills you immediately. This means that the largest square room you can have is 10x10 internal. Drawing a remove roof zone will cause colonists to remove a. So this took out 4 people.

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. 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. You didn t mine out a mountain you mined out a hill. For some reason the regular rock areas collapsed as i was mining them.
