In its armed position, it is presented as a steel cylinder with six spring-loaded fins at the bottom of the mine. It shoots out string that attach to nearby objects, which is used as a tripwire. The POM-2 mines must be delivered using remote mining systems, with the exception of POM-2R.

Function

The mine is made up of a cylindrical cast-steel cup, which contains the

Pulling on the cord with anything more than , causes the detonator to detonate the mine, dispersing fragments semi-spherically.

Deployment

Before use, the KPOM-2 cassettes are carefully checked for cracks. If any cracks deeper than 0.3 mm are present, then the cassette must be withdrawn, as it must be

UMZ

If the mining is performed with the usage of UMZ, then the machine must be moving at the speed in the range of 10–40 km/h. The interval between every launch is set in the control remote PUM-1V (). A full load (180 cassettes - 720 mines) can create a minefield that is 4,100–4,200 meters long and 50–60 meters wide, with a density of 0.1-0.2 mines/meter.

VSM-1

If the mining is performed with the usage of the helicopter-mounted minelaying system VSM-1, then the machine must be moving at a speed in the range of 160–220 km/h, at an altitude of 50–100 meters, with an interval between every cassette launch being 0.8 seconds. A full load (116 cassettes - 464 mines) can create a minefield that is 4,100–4,200 meters long and 35–65 meters wide, with an average density of 0.11 mines/meter.

PKM

If the mining is performed using the portable mining kit, then it must be performed by two or more people, supported by a sapper group.

9M59 Rockets

If the mining is performed using the

MLRS, then a full salvo (16 rockets) can create a minefield consisting of 144 mines.

words Uchebnaya (U - Rus. ''Учебная'') - training, and Inertnaya (I - Rus. ''Инертная'') - inert. Utilizes the UI-KPOM-2 cassette. ; UI-POM-2-2 or UI-POM-2A : ''Inert'' mine for ''training'' purposes. It is no different from the UI-POM-2-1, except that it has all the pyrotechnic elements. Utilizes the UI-KPOM-2A cassette. ; UI-POM-2-3 or UI-POM-2D : ''Inert'' mine for ''training'' purposes. It contains all elements as in the POM-2, except that the explosive charge is replaced with a smoke-generating substance, the explosive cap is replaced with an igniter element, and the detonator is removed. Two holes are drilled in the frame of the mine for the escape of the smoke. Utilizes the UI-KPOM-2D cassette. ; POM-2R () : Primarily issued to special forces. Used as a pursuit deterrent and can be delivered in the same ways as the POM-2, but can also be deployed manually without the usage of cassettes. The naming convention comes from the
