I and a friend have been playing Minecraft in a world together for a few days and often hear noises in a room in our house that sound like trains, but can't find a mine, etc. Does anyone have any tips on how to find them?
It's best to always brow, that's where they are mostly ^^
Mines are often found in ravines. Otherwise, like dungeons, they should be discovered by chance while digging. Correct entrances do not exist. In the table mountains, on the other hand, there are mines that are on the surface and that are easy to find.
Dig around a bit.
