Find every mineshaft in your seed
Find the abandoned mineshafts in your world. They are dense, so this map shows one layer at a time rather than burying everything else. Click any marker for its exact chunk and a teleport command you can paste straight into chat.
Mineshafts generate almost everywhere underground, which is why they are far more common than any other structure. Badlands mineshafts generate much higher and often break the surface.
Why go to a mineshaft
Rails, minecart chests with diamonds and enchanted books, and the cave spider spawners in the corridors. They are also the fastest way to explore a lot of underground quickly.
Frequently asked questions
How do I find a mineshaft in Minecraft?
Enter your world seed and every mineshaft in range is marked on the map. Click a marker to see its chunk and copy a
/tp command straight to it. Turn the biome layer on to see the terrain around it before you set off.Where do mineshafts generate?
Mineshafts generate almost everywhere underground, which is why they are far more common than any other structure. Badlands mineshafts generate much higher and often break the surface.
What is inside a mineshaft?
Rails, minecart chests with diamonds and enchanted books, and the cave spider spawners in the corridors. They are also the fastest way to explore a lot of underground quickly.
Why are there so many mineshafts?
They use a much tighter grid than other structures and are not biome-restricted, so they blanket the underground. This is why the layer is off by default on the general structure map.
Does this work for Minecraft Bedrock Edition?
Yes. Use the Java / Bedrock toggle above the map. Be aware the two editions are not interchangeable: since 1.18 they share terrain and biome generation, so the landscape for a given seed looks nearly the same, but structures like villages and strongholds use edition-specific placement and end up in different places. Bedrock also uses 32-bit seeds where Java uses 64-bit.
Is my seed sent to a server?
No. The whole map is computed in your browser with JavaScript. Your seed never leaves your device, there is no account, and no download is necessary.
Can I share a link to what I am looking at?
Yes. The address bar updates as you pan and zoom, so you can copy the URL at any time, or press Copy link. Anyone opening it lands on the same seed at the same position and zoom.
What do the grid lines mean?
The fine grid is chunks (16x16 blocks), which is the unit slime chunks and mob spawning work in. The heavier grid is regions (512x512 blocks, or 32x32 chunks), which is the unit Minecraft uses when deciding where to place structures. Brighter lines through the middle mark the world origin at X=0, Z=0.
