Cave-ins and mine supports

The server uses Interesting Ore Gen (IOG) for cave-ins. Supports and natural rock pillars let you control where you mine instead of opening an unsupported ceiling.

How cave-ins work

• Breaking a block starts an IOG search through blocks that share a face with it. The search can travel up to 20 blocks.
• If the search reaches rock at 100% instability, IOG checks downward. A cave-in can start when the bottom face of that unstable block has air below it.
• Placing a block directly below an unstable ceiling block, leaving natural rock pillars, or using Posts and Beams can prevent that block from starting a cave-in.

Using Posts and Beams

Use the wooden post blocks from Posts and Beams. Do not use decorative beams as mine supports.

1. Place a post vertically from the floor to the ceiling.
2. Attach a post horizontally to the post and extend them to the next post.
3. Keep each section of ceiling supported before removing more rock. Add another post when a beam span leaves too much unsupported ceiling.
4. Leave natural rock pillars between rooms and along the route to the ore.

Wooden beams must remain connected to a post or they break. Place the posts first, then attach the beams. Keep the support visible so it is easy to see which ceiling blocks are covered.
