The Top of the Mine

This series of pictures show the top of the OZM-3 mine.  The picture to the right is the mine as it is normally stored.  The electrical fuze well is the dark circle on the right.  Wire is set into this point when the mine is to be command detonated via an electric current.

The picture below shows the mine with the cover of the mechanical fuze well removed.  While the picture on the bottom right show the mine with the MUV-1 fuze attached.

OZM-3 Mine Bottom

This picture shows the underside of the OZM-3 mine.  The center plate and inner ring in the is where the explosive bounding charge is housed.   This charge is permanently  screwed into the mine at the factory.  The outermost ring is the fragmentation sleeve that bounds into the air before exploding when it is set off.

Mine Markings

These close-ups show the markings that can be found on the mine.  On one side is the Mine's designation along with a production code.  In this case this mine was made in 1966.  The opposite side of the mine has only a simple white band.  I don't know if this denotes this example as a training mine or if it even means anything at all.

The MUV-1 Detonator

The item on the top right is the MUV-1 mechanical detonator.  It is a simple spring loaded striker that is held back by a retaining rod or small branch, or similar item tied to a tripwire.  

When the trip wire is pulled and the rod is removed the striker is released.  It then hits a primer within the mine that sets off the main charge.  It is used on a variety of mines, and is also used on the bottom of certain anti-tank mines as an anti-handling device.

The lower picture is a view of the MUV when it is fully disassembled.  It is a very simple device.
