PULSE NON-EXPLOSIVE SURFACE SEISMIC SOURCE Russian patent published in 2009 - IPC G01V1/155 

FIELD: mining.

SUBSTANCE: invention is related to the field of non-explosive pulse seismic sources used in performance of seismic survey. Pulse non-explosive surface seismic source comprises rigid base, kentledge with cantilever resting on it and electromagnet drive with power supply circuit. At the same time base is made of dielectric material with groove on surface that faces kentledge, in which mentioned drive excitation winding is placed. On surface of kentledge that faces base there is a plate made of electroconductive material, end of kentledge cantilever is connected to base with the possibility of angular displacement between them, and between kentledge and base there is a single-sided damper. Moreover, excitation winding may be arranged of several coils, every of which is placed into a separate slot on base.

EFFECT: reduction of base weight, elimination of impact processes between anchor and inductor of electromagnet converter and provision of higher maximum value created o base-radiator of mechanical force that determines seismic efficiency and possibilities of seismic source application.
