SEISMIC WAVE GENERATING APPARATUS AND METHOD

摘要

A seismic wave generating device (1) and methods for generating seismic waves having a relatively strong longitudinal energy and a relatively weak transverse energy are disclosed. A device (1) may have a hollow casing (10) and a striking member (40) passing through the hollow casing (10), the striking member (40) or the hollow casing (10) bearing a spacing member (30). A method may drive the hollow casing (10) into the earth, then remove earth from within the hollow casing (10). The method may place a striking member (40) through the hollow casing (10) and may drive the striking member (40) further into the earth to create seismic waves with a relatively strong longitudinal energy and a relatively weak transverse energy.
