A camouflet, in military science, is an artificial cavern created by an explosion; if the resulting structure is open to the surface it is called a crater.
The term was originally defined as a countermine dug by defenders to prevent the undermining of a fortress's walls during a siege. The defenders would dig a tunnel under the attackers' tunnel. An explosive charge would be detonated to create a camouflet that would collapse the attackers' tunnel.
