How to get dwarves to find missing dwarves

You need two things in addition to the picks.

• Dwarves with the mining labor enabled, as explained here.
  • The dwarves might be busy with other things, try turning off other labors.
• An area designated for digging.
  • You can designate an area for digging by pressing d, d and selecting an area to be mined. This is easiest if you have an exposed hillside on the map. If not you may need to go down a z level and designate ramps up (d, r) next to your mining area.
  • The dwarves must be able to path to this digging area. If it is separated by z-levels, you must add stairs or ramps.

Infections can heal on their own, but not always. The best method is prevention, which means having soap in your hospital so the doctors clean their wounds (and hopefully prevent infection).

If your dwarves ever become "pale" it means that death from infection is imminent.
