A device for resafing an armed mine (3). The device comprises a resafing means (2) for performing a resafing movement in the mine, an electric motor (1) for providing said resafing movement, and a battery (5) for powering the electric motor. An artificial load (8) is connected across the battery (5) and is by means of a timer circuit (4) intermittently transformable from a normally non-conductive state to a conductive state. The artificial load is dimensioned to draw, in its conductive state, substantially as high electric current from the battery as the electric motor (1) draws during the resafing movement. A comparator (12) is provided to compare the battery voltage to a reference voltage (Vref), and to deliver a resafing signal to the electric motor when the battery voltage falls below the reference voltage in order to initiate the resafing movement.
