FIELD: seismology. SUBSTANCE: invention is intended for excitation of seismic waves in rock mass in any point of borehole to increase intensity of lateral waves in direction perpendicular to borehole axis. Borehole gear includes rod, body housing partitions, two springs, outward pressure unit with contact members mounted for translation along gear axis, locator, another rod, auxiliary rod, supporting plate. EFFECT: simplified design, improved operational efficiency. 1 dwg
