FIELD: mining.
SUBSTANCE: invention proposes a method for probing, logging of rocks and positioning of a missile in a drill well, which involves generation of electromagnetic and magnetic fields by means of a radiating antenna and an inductor in the form of a constant magnet or an electromagnet, remote measurements of parameters of these fields by means of receiving antennas, three-axis magnetometers and gradiometers installed at check points of observations on the ground surface, and further calculations based on the multidimensional information obtained at measurements as per the corresponding algorithms of parameters of identified rocks and parameters of spatial position of the missile in the drill well. The radiating antenna and the inductor are arranged on the missile in the drill well and isolated from drill pipes by means of a non-magnetic insert.
EFFECT: simpler technology for receiving multidimensional information and its processing.
