ABSTRACT OF THE DISCLOSURE An arrangement for programming the control of a mine including a pin (16) made of a material having a predeter- minable magnetic permeability and inserted into a blind bore- like opening in a mine housing (12). Via a coil disposed in the interior of the mine and surrounding the blind bore-like opening, a resonant output frequency (fR) of an oscillator, which frequency is a function of the permeability of the pin (16), is generated. If the detected resonant output frequen- cy (fR) corresponds to a frequency (fi) stored in a frequen- cy/address memory (42), an address (Ai) associated with this frequency (fi) is read out and fed to a read-only memory (44). This determined address (Ai) causes information (Ii) associated with this address (Ai) in the information memory (44) to be read out so that the action belonging to the respective information (Ii) is initiated within the mine.
