The Ultimate AFK Mining Dimension

The Mining Dimension — The Ultimate AFK Mining Dimension

  A flat, perfectly safe, mob-free mining dimension for 1.20.1 (Forge). Dig endlessly without caves, mobs, lava, or darkness. AFK-mining has never been this easy!**

+
- ⛏️ **Diamonds concentrated deep**, **ancient debris in huge clusters**

🎮 How to Use
+
+
1. Place a **Crying Obsidian** block in the overworld
+
2. **Sneak + Right-click** it with **empty hands**
+
3. You teleport to the mining dimension at the **same X/Z**, standing on the surface (Y64)
+
4. A **return portal** (crying obsidian) is automatically placed next to you — sneak + right-click it to go home
+
5. Return to the **exact same crying obsidian** you used to enter — no lost coordinates, no extra obsidian piling up
+
+
 💀 **Died in the mining dimension?** You respawn back in the overworld at your portal.

+
| Y-129 – Y-255 | **Pure netherrack layer** | Nether ores: **Ancient Debris (dense clusters)**, Nether Gold, Nether Quartz |

❓ FAQ
+
+
**Q: Do I need to bring materials to come back?**
+
A: No! A crying obsidian return portal is automatically generated next to you.
+
+
**Q: Will the overworld get covered in obsidian?**
+
A: No. The overworld never generates obsidian — you always return to the one you placed.
+
+
**Q: Can I bring a quarry / auto-miner / use TNT?**
+
A: Yes! Everything works — vanilla pickaxes, Efficiency, quarry machines, TNT.
+
+
**Q: Is the world stable for AFK?**
+
A: Yes. Chunk generation is deterministic and never resets while you are away.
