Abandoned Mineshafts are generated structures that generate in the Overworld.

Generation

Abandoned mineshafts generate naturally in the Overworld, they are usually found underground but some can be found in the ocean. They are generated before chunk features such as ores. As with other features, multiple abandoned mineshafts 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 Pocket Edition and PC [[Template:1.10]]‌[upcoming], they can spawn on the surface in mesa biomes. These are composed of dark oak planks and fences, rather than oak.

Mineshaft

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 oak 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.

  1. a b c The size of stacks (or for unstackable items, number) of this item on any given roll.
  2. a b c The weight of this item relative to other items in the pool.
  3. a b c The odds of finding any of this item in a single chest.
  4. a b c The number of items expected per chest, averaged over a large number of chests.
  5. a b c The average number of chests the player should expect to search to find any of this item.
  6. a b c All enchantments are equally probable, including treasure enchantments (except Soul Speed, and Swift Sneak), and any level of the enchantment is equally probable.
  7. a b c 'Nothing' does not refer to the chance of an empty chest. Instead, it refers to the chance that the random loot generator does not add any loot on a single roll.
  8. Enchanted with a random level of Efficiency.


Video

Note: The video shows that cocoa beans are generated in chests, this is false. Also, floating mineshafts were removed in 1.2.1. Lastly, chests were replaced with minecarts with chests since 1.5.

Trivia

  • At bedrock layer, abandoned mineshafts will cut through the top bedrock layer(s).
  • Mineshafts 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]
  • Mushrooms can be found at the bottom of mineshafts.

Publicity

  • In LEGO Minecraft Micro World- The Village, an abandoned mineshaft is beneath the village.
