Lists on the subject

The PGMDM , or PTM-1, is a remotely deployable anti- tank mine made in Russia.


The PGMDM has a lead body made of polyethylene with an elongated conical shape. On the front side there is a cylindrical metal cap as a detonator cover. The mine can be sand-colored, olive, green or brown and is triggered by pressure or self-destruction. It weighs 1.5 kg and contains 1.1 kg of PVV-12S - liquid explosive . It has the same detonators as the anti-personnel mine PFM-1 . These are either the VGM pressure detonator or the VGMS-572 time detonator with a trigger time of 3 to 40 hours. The trigger pressure is between 120 and 160 kg.


  • PTM-1: 1st series version with liquid explosive and cumulative 57-B-418 pressure detonator
  • PTM-1S: 2nd series version with additional time fuse. Self-destruct after 3–40 hours
  • PTM-1G: 3rd series version with PVV-12C-1 - plastic explosive and new 57-B-420 igniter
  • PTM-3 : Successor model with magneto and anti-lift

Use and function

Three leads each are housed in a 48 cm long KPTM-1 cassette. The cartridge has an ejector charge for the mine and is remotely deployed by vehicles, helicopters, airplanes, or missile artillery. After being ejected from the cassette, the mine automatically unlocks itself after 60 to 100 seconds. When pressure is applied to the mine body and the liquid explosive it contains, the fuse ball of the detonator is pressed into a recess, which releases a preloaded firing pin and strikes a detonator which then ignites the charge.

Areas of application
