HomeMINES and CHARGESSOVIET & BALKANRussia

The TMD-B wooden antitank mine was first employed by the Soviets against the Germans in 1943, and later was one of the four Soviet mines used in Korea.



It is of simple wooden construction and the boards are nailed together or fastened by tongue and groove joints.
The mine has three pressure boards on the cover. The center pressure board is hinged to permit insertion of the fuze.
When the mine is armed, the hinged pressure board is held shut by a wooden locking bar.
The main charge normally consists of two waterproof, paper-wrapped blocks of pressed amatol, dynamon, or ammonite.
In Korea, however, some of the TMD-B mines were filled with TNT blocks, cast TNT, picric acid, or other explosives.
The booster charge is normally a
200g (7oz) TNT block.
The TMD-B, which may be factory or field manufactured, employs an
MV-5 pressure fuze and an MD-2 detonator.
A very similar mine, with a centrally located plastic fuze well cover and only two pressure boards, is known as the TMD-44.
A similar Czechoslovak mine is called the
PT-Mi-D.
