SEISMIC WAVE GENERATING DEVICE FOR GEOLOGICAL SURVEY AND THEREOF

摘要

PROBLEM TO BE SOLVED: To extend distance that can be prospected due to the conveniences of execution in a resource device for geological survey. SOLUTION: A first transfer substance 9 consisting of a fluid body is filled into an seismic wave generating container 6, and a second transfer substance 15 consisting of a solid whose traveling acoustic wave speed differs from that of a the first transfer substance 9 is provided on the inner-periphery surface of the seismic wave generation container 6, thus extending shock time when the traveling acoustic wave based on the shock being generated when a metal small-gauge wire 8 is melted and vaporized is mixed outside the seismic wave generation container 6 and is propagated to a prospecting region, reducing attenuation for the distance of the amplitude of the traveling acoustic wave, and extending prospecting distance.
