Most Soviet vibration mines are wooden boxes which are divided into upper and lower compartments;
the upper, containing the vibration contact fuze wired to an electric detonator and the lower containing the explosive charge.

These mines can usually be recognized by the lack of pull wires or protruding pressure pieces on the mine body.
The DM mine is one of these mines; the additional fuze is the
ChVZ vibration delay fuze.
It has one hole in the dividing partition for the short electric leads that connect to the electric leads that connect to the electric detonator.
Another hole in the top is for the long arming wire leads from the fuze.
This mine is designed to be laid in roads, bridges, culverts, and other places where vehicular traffic will set up enough vibration to actuate the fuze.
Since the mine shows no exterior evidence of its fuzing, and any jar or tilt will be likely to close the electrical circuit, hand disarming should not be attempted.
When used against tanks or trains, the DM mine is usually laid on an additional charge.
