Fire in the hole什麼意思

"Fire in the hole" is a warning phrase that is used to indicate that explosives are about to be detonated. It is most commonly used in mining and construction operations where explosives are used to break up rock or concrete. The phrase is meant to alert anyone in the vicinity to take cover and protect themselves from flying debris or other potential hazards.

The origin of the phrase is somewhat unclear, but it is thought to date back to the early days of mining when candles were used as a source of light. If a miner noticed that the candle was flickering or dimming, it could be a sign that there was a buildup of flammable gases, which could potentially explode. In such a situation, the miner would yell "fire in the hole" to warn others in the area.

Today, the phrase is still used in a variety of contexts where explosives are being used, such as in demolition, quarrying, and military operations. It is a critical safety measure to ensure that everyone in the area is aware of the impending explosion and can take appropriate action to protect themselves.
