Anti-Personnel Mine “OZM with UVK”

The “OZM with UVK” mine is a command-detonated bounding anti-personnel fragmentation mine with all-round effect. It is intended to incapacitate enemy personnel. A person (or several persons simultaneously) is struck by fragments of an artillery shell when it detonates at a height of 60-80 cm above the ground surface after being projected by a powder expelling charge, which is initiated by an electrical impulse from a control panel. The mine consists of an artillery munition connected to a UVK universal ejection chamber.

The basis of the mine is the UVK universal ejection chamber, onto the threaded bushing of which an artillery shell is screwed.

The universal ejection chamber (UVK) is used for the emplacement of anti-personnel fragmentation mines using artillery shells and mortar bombs. Soviet and Russian fragmentation and high-explosive fragmentation shells of 85, 100, 115, 122, and 152 mm calibers, as well as 82 and 120 mm mortar bombs, are used. When 152 mm shells are used, ejection from the ground is not ensured (the shell detonates in the ground).

The mine is emplaced manually in the ground, and if emplacement in the ground is not possible, on the ground, with the mine placed in a wooden box.

The shells are supplied separately. The “OZM with UVK” mine is assembled at the emplacement site.

As a rule, such mines are used to create a command-controlled anti-personnel minefield. When enemy soldiers enter the lethal zone of one of the mines, the operator actuates the mine by means of the control panel.

Principle of operation:

When an electrical current impulse is supplied through the wires, the electric igniter is initiated, and from it the ejection charge is ignited. The pyrotechnic delay element is ignited by the ejection charge. Under the pressure of the propellant gases, the body of the UVK chamber ruptures along the welded seam, and its upper part, together with the detonating device and the shell (bomb), is ejected from the ground. After the delay element burns out (0.3-0.45 seconds), the flame jet from it causes the detonation of the detonator and the explosive charge of the shell (bomb). The explosion of the explosive charge shatters the shell body into fragments which, as they disperse, strike enemy personnel.
