PMN-4 Russian Anti-Personnel Mine
PMN-4


The PMN-4 is a delay-armed, pressure-fired blast-mine. The pressure-plate is black and the body is reddish-brown or khaki. The black rubber pressure-plate has a plastic pressure "spider" concealed underneath, shaped like flower-petals. The diameter of the mine is 95mm and the height is 46mm. The explosive charge weight is 55 grams. This comprises 52 grams of 'TG-40' (a 40/60 TNT/RDX mixture) plus a 3 gram pentolite booster. The total weight of the mine is 300 grams. PMN-4 mines contain a significant amount of metal components, so they are readily detectable with a mine detector. Details of the fuze mechanism are scarce, though given that the PMN-4 was designed during the early 1980s, it is logical to assume that the fuze is more sophisticated and/or reliable than the fuze in the PMN-2 (a mid-1970s design) to compensate for having a smaller explosive filling with significantly reduced destructive power. Similarly, the PMN-4 is almost certainly a blast resistant mine due to the design of the flower-shaped pressure "spider" under the pressure-plate.[2] Cross-sectional diagrams of the PMN-4 showing its components support the view that the PMN-4 is a more sophisticated design then the PMN-2.Examples of the PMN-4 have been encountered in Ukraine and Southern Syria.
