      ATTENTION Forum Database Breach   03/04/2019

      There has been a breach of our database. Please make sure you change your password (use a password manager, like Lastpass).
      If you used this password anywhere else, change that too! The passwords themselves are stored hashed, but may old accounts still had old, insecure (by today's standards) hashes from back when they where created. This means they can be "cracked" more easily. Other leaked information includes: email, IP, account name.
      I'm trying my best to find out more and keep everyone up to date. Discord ( is the best option for up to date news and questions. I'm sorry for this, but the damage has been done. All I can do is try to make sure it doesn't happen again.

[Solved] Support beams in multiple layers

2 posts in this topic

I have a question about support beams. I found some surface copper and dug a hole straight down to the middle layer of stone, where I eventually found two blocks of native copper. I mined out a 3x3 spot and placed a support beam, then dug out in all directions. All I ever found were the two blocks of copper. After finally using my prospector's pick (duh) I know there is a very large sample of copper down here, and in looking for more advice online I now realize I probably needed to go a little deeper to get the main vein (also maybe some distance x or z). Can I create a mine with multiple vertical layers without getting cave-ins? If I continue my hole straight down five or more blocks and then start to dig outward again, will I be undermining (ha) my existing support beam above? I don't really understand the physics of digging down below an existing support beam.

Generally speaking, digging down is only dangerous is there is space below you, above doesn't really matter. Even if you do manage to cause a collapse that breaks the blocks under your support beams, that isn't going to cause the higher ceiling to collapse too.
