The tool has a programmable micro-controller circuit (8), magnetic senor (5) to sense external setting signals and setting tool which transfers pulses when in the proximity of the magnetic sensor. The magnetic sensor is position in the fuse housing (1) of the mine. the setting tool is in the form of a code-bar. The fuse housing has a cover plate (2). The magnetic sensor is connected to the programmable control circuit suitable for setting the operation time.
