Abstract
The invention consists of initial part (2B), which at the lower side is made in pyramid form and is part of mine activating mechanism (1). At its screwing into mine body (3), ampoule (D2) containing the aggressive matter is broken by the sharp point, the matter spills and comes to initial part (2B) that gets immersed in it. The aggressive matter slowly corrodes the walls of initial part (2B) and, when it corrodes them through, it mixes with the initial explosive placed inside initial part (2B), soaks it and neutralizes it, in such a way the initial explosive looses its explosive properties, and the mine cannot be activated any more. Cylindrical housing (D) serves for placing ampoule (D2) and retaining the aggressive liquid after breaking ampoule (D2).
