An ejected mine (10) is provided with erection elements (28-28V) which are folded up on the mine while said mine is being laid and are subsequently released to spread apart in order to erect the mine (10) in the active direction. On the other hand, the mine has sensors (16, 16', 16'') which are arranged in recesses (14, 14', 14'') and are used to trigger the mine. In order to protect these sensors (16, 16', 16''), the erection elements (28, 28'', 28IV) which are arranged at the same pitch as the sensors are provided with covering elements (34', 36) which protect the sensors (16, 16', 16'') from being damaged and prevent the corresponding recesses (14, 14', 14'') from being blocked (Figure 1).
