FIELD: systems of hole drilling in the Earth's crust. SUBSTANCE: system has the first subsystem including drill string run into hole and the second subsystem including system of drive for rotation of drill string round its longitudinal axis. Resonance rotation frequency of the second subsystem is lower than that of the first subsystem. EFFECT: developed system for hole drilling in the Earth's crust featuring reduced tendency of intermittent moving of drill string in hole. 11 cl, 3 dwg
