Dangerous gases such as [[methane]] can accumulate in mines and can explode if ignited, and the inhalation of dusts is also a health issue, so underground mines must be ventilated, typically with large fans located above ground which keep air circulating through the mine.

In addition, mines must be inspected for unstable conditions which might result in a cave-in, and other hazardous conditions.
