coal mine
Black rock pit
A coal mine is an excavation where coal is extracted from the earth, either underground through tunnels and shafts or at the surface through open pits.
The phrase canary in a coal mine refers to an early warning sign—miners once brought canaries underground to detect toxic gases, since the birds would die before gas levels became lethal to humans.
