FIELD: machine building.
SUBSTANCE: invention relates to the field of engineering, and more specifically to stationary signal signs. Device for marking the boundaries of a minefield includes body (1), cup (2), electromechanical retarder (3), placed in cup (2) and having the ability to work after a specified period of time, expelling powder charge (5). Piston with rod (6) is mounted to move to the highest position. Sign with reflective shell (7) has the ability to appear above the ground surface, and sign (8) is fixed in tides (11) on body (1) and rises above the ground.
