Coal Mine

Tech Level 37. Some wiki pages call this a Coal Quarry; same station either way, and it's the passive Coal bay that finally frees you from node hopping for furnace fuel.

The usual recipe is Stone ×70, Coal ×100, Paldium Fragment ×30, and Ancient Civilization Parts ×10. Mining runs it. SAN drain is commonly cited near −0.15, and the product is Coal for Refined Ingot recipes and general smelting.

Pair the mine with Ore Mining Site II so Ore and Coal arrive in the same Transport loop. Feed Improved Furnace, Electric Furnace, and later Gigantic Furnace without sending Mining Pals on another field trip. If you still need wild nodes while the station catches up, use our best coal base locations guide, then retire the commute once the quarry is staffed and fed.
