The third in a series of abandoned mine shafts, once prosperous before the Great War.
Abandoned mine shaft 3 is a former mining operation. It is currently occupied by mole miners. Outside the building, a small cooking station can be found by the western door, a wood pile along the southern wall, and an armor workbench by the eastern door. Inside, there is a bed, a desk with a radio jammer on it, and a locked chem box. To the south of the building is a refinery. A little further south is a modern art exhibit, the office of which is an orange train car sitting on the western side.
Abandoned mine shaft 3 appears only in Fallout 76.
