Abstract
A mine, particularly a land mine, is equipped with at least one active (i.e. destructive) element which is accommodated in a housing of the mine and can be brought to the functional level by means of a rocket engine. For attaining a definite ascent of the active element, the rocket engine is mounted to this active element in such a way, and is designed in such a way, that its exhaust nozzles are located outside the mine housing and the propellant gases of the rocket engine effect extraction of the active element from the mine housing which is open at an upper end. The rocket engine furthermore exerts preferably a torque on the active element about the longitudinal axis of the element so that, in conjunction with an effective charge, the effective direction of which is inclined obliquely downwardly, the effective area on the ground continuously increases in a spiral fashion during ascent of the active element.
