Abandoned Mineshafts are generated structures that generate in the Overworld.


Dungeons generate naturally in the Overworld, almost anywhere underground. Abandoned mine shafts are generated before chunk features such as ores. As with other features, multiple abandoned mine shafts can generate near each other and intersect, producing larger complexes. They can also intersect with other cave systems. Corridors will generate a floor of wooden planks if they cross over empty space.

In the Pocket Edition, they can spawn on the surface in Mesa biomes.[upcoming]

Abandoned mine shafts consist of:

  • A starting point - a large room with a flat dirt floor, an arched ceiling and up to four exits (one in each direction, although, sometimes it generates in a way for up to five entrances.)
  • Corridors - 3×3 block corridors featuring supports made from fences and Wood Planks (sometimes complementary with torches), broken rails, minecarts with chests (containing resources) and cave spider spawners surrounded by cobwebs.
  • Crossings - intersections with wooden pillars, sometimes two floors tall.
  • Staircases - diagonal sections of tunnel.


Each chest contains 3-6 stacks of items, chosen from the following list. Chance listed is per stack, not for the chest as a whole.

  1. Enchanted books in the same chest will have the same enchantments. Enchantment probabilities are the same as a level-30 enchantment on an enchantment table, but the chance of multiple enchantments is not reduced.

Issues relating to "Abandoned mine shaft" are maintained on the issue tracker. Report issues there.


  • Small underwater air pockets can be found in the sea, which are caused by failed entrances to mineshafts.
  • At bedrock layer, Abandoned Mineshafts will cut through the top bedrock layer(s).
  • Mine shafts can generate on top of other mine shafts. If you see two different ones intersecting each other anomalously, they are two different shafts, even if they somehow meet up perfectly elsewhere.
  • Mineshafts are less common near the origin of the world (0,0).[Verify]


  • In LEGO Minecraft Micro World- The Village, an Abandoned Mine Shaft is beneath the Village.
