Exploring the Ancient Mines Structure in Integrated Dungeons
guide
The Ancient Mines in Integrated Dungeons and Structures is a rare subterranean dungeon featuring multi-tiered mining galleries, hostile monster spawners, and hidden chests containing the elusive 
Disc Fragment Slither.
Generation and Structural Spacing
The Ancient Mines structure generates deep underground across Overworld biomes within the stone and deepslate strata:
- Classified under the rare structure set with a spacing interval of 45 chunks and a minimum separation of 20 chunks.
- The structure features a surface entrance outpost that funnels adventurers downward into sprawling multi-level excavation shafts.
- Unlike vanilla abandoned mineshafts that generate as narrow wooden corridors, the Ancient Mines features expansive vaulted caverns supported by heavy stone arches and scaffolding.
- The complex branches out into ore processing chambers, underground rail hubs, flooded drainage basins, and private foreman offices.
- Excavation shafts frequently intersect natural deepslate caves and subterranean lava pools, creating hazardous navigation choke points.
Subterranean Hazards and Monster Ambush Tactics
Raiding the Ancient Mines presents formidable survival challenges:
- The structure overrides default mob spawning rules with intensified monster ambushes, placing custom spawners behind reinforced prison grates.
- Skeletons armed with enchanted bows perch on high wooden cat walks, targeting players crossing rope bridges across dark chasms.
- Cave spiders infest abandoned web-covered support tunnels, while armored zombies guard central rail junctions.
- Hidden pressure plates trigger ceiling gravel traps, falling anvil hazards, and explosive TNT minecart ambushes along dark railways.
- Explorers should carry water buckets, fire resistance potions, plenty of torches, and a high-durability shield before descending into lower galleries.
Salvaging Treasure and Restoring Music Discs
Conquering the central vault of the Ancient Mines yields high-value survival loot:
- Supply chests hidden in foreman desks and rail carts contain diamond tools, enchanted books, golden apples, and raw ore caches.
- Most importantly, the deepest treasure chests within the mine vault hold rare fragments of Disc Fragment Slither.
- Gather nine individual pieces of Disc Fragment Slither across your dungeon explorations.
- Arrange nine pieces of Disc Fragment Slither in a three-by-three crafting table grid to assemble a complete
Music Disc. - Insert the restored Music Disc into any standard jukebox to play the unique atmospheric soundtrack recorded for the mod.
