IMPULSE NON-EXPLOSIVE GROUND SEISMOSOURCE Russian patent published in 2004 - IPC

FIELD: generation of seismic waves at seismoprospecting operations.

SUBSTANCE: the source has a rigid base-radiator of seismic waves, sticked load, self-contained electric power supply system and a power electromagnet, whose force is transmitted to the base. The electromagnet inductor is fastened on the sticked load, which rests on the base and is made with a cantilever. The end of the cantilever is coupled to the support on the base by means of an axle. The movement of the sticked load upwards at operation of the seismosource is accompanied by arising of inconsiderable frictional forces in the axle connection, which provides for an effective excitation of seismic waves both in the horizontal and non-horizontal positions of the base on the ground (at operation on a cross country).

EFFECT: enhanced durability, reduced frictional forces counteracting the movement of the sticked load, provided effective operation in the non-horizontal position of the base.
