About Fire in the hole
"Fire in the hole" is an expression indicating that an explosive detonation is imminent. It originated from American miners, who needed to warn their fellows that a charge had been set. The phrase appears in this sense in American state mining regulations, in military and corporate procedures, and in various mining and military blasting-related print books and narratives, e.g. during bomb disposal or throwing grenades into a confined space.
