The command you posted had some serious formatting issues. I went ahead and fixed them.

NPCPassive This tag should only prevent your Dwarf Miner from attacking NPCs. Other NPCs should still attack the Dwarf Miner normally.

Invulnerable I'm pretty sure it wasn't working because of your incorrect formatting. Use the above command and try again.
