Rimworld Mining Roof

So if you mine a roof that has already collapsed it re collapses and kills you immediately.

Rimworld mining roof.

This means that the largest square room you can have is 10x10 internal. So this took out 4 people. You didn t mine out a mountain you mined out a hill. 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.

Roof collapses cause injuries to colonists and damage items. For example plasteel yields 7 units per cycle making it effectively 5 times slower to mine than steel which yields 35. Drawing a remove roof zone will cause colonists to remove a. A roof will collapse if the last supporting wall or rock is removed whether by mining deconstruction or destruction.

If it s an overhead mountain collapsing colonists will be buried alive. Any square 9 x 9 or bigger should have 1 support right in the middle. So i then took some guys and mined the collapsed roof at which point they each died as they finished their square. A roof collapses if there s no support rock wall within 6 squares of the tile.

You can avoid a collapse by either not mining the whole thing or building a wall to support it. 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. Although this time is the same for all materials the amount per cycle varies. What can i do about this.
