Height : 260mm
Main charge: 425g TNT/RDX
The mine uses an UPROM-1 fuze that may also be designated UPMR-3.
It is usually supplied with 2 rolls of plastic coated tripwire
each 16m long.
The mine is initiated by tilting the prongs at the top of the
fuze. This can be done by direct pressure or by pulling a tripwire.
More than one tripwire can be attached to the same fuze. On
initiation, the mine body is thrown into the air leaving the
base plate in the ground. The body is tethered to the base plate
with a wire (around a metre long). When the wire is pulled tight,
that initiates the main charge and the body of the mine fragments
in a 360 degree radius.
mine has been responsible for the deaths of more deminers than
any other mine on record. Most fatal accidents have occurred
by striking the fuze-prong while cutting undergrowth, or while
attempting to re-fit the safety collar (improvised clips seem
