The mine is laid only on the ground by PKM-1, VSM-1, or UMZ remote mining systems, in remote mining cassettes of the 220 mm Uragan multiple launch rocket system (MLRS).
When PTM-1 mines are employed by PKM-1, VSM-1, and UMZ systems, the KPTM-1 cassette is used, which contains 3 PTM-1 mines
In the 9K57 Uragan MLRS, 9M27K2 and 9M27K3 rockets are used for PTM-1 mines. They contain 24 PTM-1 mines and have a firing range of 7 to 34 kilometers
On the ascending portion of the rocket flight trajectory, the warhead separates, and the mines are ejected from the casing by a pyrotechnic cartridge. At this point, the process of switching the mines to the armed state begins, which is completed 60–100 seconds after the mine contacts the surface.
The 9K57 Uragan MLRS has 16 launch tubes. The salvo duration is 9 seconds. One launcher, in a single salvo, lays an anti-tank minefield of 384 mines with dimensions of 400–900 meters along the frontage and 600–900 meters in depth. The average distance between adjacent mines is 23–24 meters.
The mine is equipped with a self-destruct mechanism.
The mine is weak in terms of explosive weight characteristics. When the mine detonates under a tank track, only one or two, rarely three, track links are destroyed. Often it does not sever the track, but only damages it. A BTR-80 wheel running over the mine causes damage only to the wheel tire. The BTR itself fully retains its mobility.
The mine is dangerous to personnel due to the possibility of the self-destruct system functioning while the mine is near a person. When this will occur is unknown; therefore, approaching, manually dragging away, or rendering the mines safe is prohibited.
To clear the mines, roller mine plows of the KMT-5M (KMT-7) type or mine-clearing line charges of the UR-67, UR-77 systems or similar systems must be used. It must be taken into account that deep snow cover, dense shrubs, tall grass, or marshy ground may result in soil (snow) being under the mines, preventing the track from applying the required pressure to the mine. Under such conditions, 16 to 40% of the mines may be affected. Mines that have not self-destructed may be destroyed by firing at them with small arms from a safe distance.
Coloring
The mine may be painted green, gray-green, yellow-gray, or brown-gray.
Marking
Primarily technological, in black letters or embossed (OTK stamp, etc.). The designation PTM1G is rarely present.
