This work addresses the issue of geological exploration and search of rich ore deposits. One of the effective methods is the use of the logging principle, which consists of: a well is drilled in 25-35 cm diameter, then the good side face is studied, i.е. the ore percentage is determined on the good height. The logging unit specified in this work consists of a main stepper motor, reducer, winch, and a shell with a telescopic sensor. The sensor consists of ionizing radiation sources, the proportional counter used for the detector, a preamplifier, and a sensor movement stepper motor. A motor implements an important function, consisting of lowering and lifting the logging instrument into the well. Therefore, a motor control function composition, the movement of which will reconcile with the movement of sensor movement motor. The work process covered research on developing a new method and technology of computer control, and information processing of logging unit, an X-ray radiometric logging unit mathematical model and control function was developed. The study results can later be used in creating automated mobile logging units that can be used in the mining metallurgical industry.
