Cutaway model of a Hungarian GYATA 64 anti personel mine. The Body of the mine is (1) made of brown bakelite, and the mine has a black rubber cap witha build in bakelite pressure cap (2) on top.
When the mine is laid in the ground, the safety pin (3) is removed. The firing pin (4) now becomes springloaded (5). The firing pin housing has a machined slot which (6) houses a lead strip (7) that forms a lead shear arming delay. This delays the arming of the fuze 2 minutes at +40 degrees celcius and 240 minutes at -20 degrees celcius. A closing cap (8) keeps the inner works of the mine moisture free.
When the lead wire is cut through, the firing pin moves forward until stopped by the vertical silder (9). A threaded hole opposite of the firing pin houses the screw (10) with the duplex detonator (11). The firing pin is kept from reaching the duplex detonator by the vertical slider (9) in it’s upward position. This slider has a hole through which the firing pin fits in it’s lower position, however in it’s upper position only the point of the firing pin fits into a small slot (12) machined into the lower part of the vertical slider.
If a person steps on the pressure plate of the mine, the pressure plate is levered -either pushed straight downward-, pushing down the vertical slider against the blade spring (13) and allowing the firing pin to fall into the hole and reach the duplex detonator. This will explode the main TNT charge (14) of the mine.
When in stock, the duplex detonator screw is replaced by a transport screw (15).
The mine is a simplified copy of the Russian PMN mine. It has been used in Mozambique, Angola and Lebanon. In contrast to the smaller mines that have a tipicallt 40 to 60 gram charge, this mine will not blow off a foot or leg, but kill.
Diameter body : 106 mm
Length measured over fuze : 142mm
Heighth : 61mm
Weight : 450 grams
Explosive charge : a block of 150 grams TNT on both sides of the fuze
Activation pressure : 5 kg
