Rimworld Mining Roof

Although this time is the same for all materials the amount per cycle varies.

Rimworld mining roof.

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. So if you mine a roof that has already collapsed it re collapses and kills you immediately. You can avoid a collapse by either not mining the whole thing or building a wall to support it. 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.

You didn t mine out a mountain you mined out a hill. A roof collapses if there s no support rock wall within 6 squares of the tile. Drawing a remove roof zone will cause colonists to remove a. Any square 9 x 9 or bigger should have 1 support right in the middle.

For example plasteel yields 7 units per cycle making it effectively 5 times slower to mine than steel which yields 35. For some reason the regular rock areas collapsed as i was mining them. 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. This means that the largest square room you can have is 10x10 internal.

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. Roof collapses cause injuries to colonists and damage items. So i then took some guys and mined the collapsed roof at which point they each died as they finished their square. If it s an overhead mountain collapsing colonists will be buried alive.
