PMN-2
The PMN-2 mine casing is made from injection-moulded plastic. In general, the colour is leaf-green, but occasionally brown examples may be encountered. The top of the mine has a black rubber X-shaped pressure plate. The filling is an RDX/TNT based explosive that is quite similar to Composition B. As with the PMN-1, the PMN-2 has an unusually large explosive filling when compared to many other anti-personnel landmines.
One significant difference between the PMN-1 and PMN-2 is that the PMN-2 (an early 1970s design) contains a more modern fuze with an integral baffle beneath the pressure plate. This and the X-shaped design of the pressure plate makes the PMN-2 much more resistant to traditional explosive mine countermeasures, which use sudden overpressure to detonate mines. It can therefore be regarded as a blast resistant mine. In contrast, the PMN-1 (a 1950s design) can successfully be cleared by such methods.
The PMN-2 fuze features an arming delay of approximately 60 seconds. When the arming key is rotated and removed from the mine, the arming pin is sheared. This allows the air-bellows inside the mine to be inflated by the compression spring, which in turn lifts a “safety” bar from the path of the slide, unblocking its travel. The arming delay on a PMN-2 is significantly shorter than that of a PMN-1.
