METHOD OF BOREHOLE SESMIC EXPLORATION WORKS Russian patent published in 2008 - IPC G01V1/40 

FIELD: mining engineering.

SUBSTANCE: vibration source installed in the near-surface region excites elastic oscillations. The vibrations are recorded by a probe in the receiving points located in the well. The vibrations are recorded when the instrument is in a specified position in relation to the vibration source. Moreover, the vibration source is successively induced in several points whose coordinates are determined so that valuable waves are reflected in the points with defined coordinates.

EFFECT: enhanced accuracy of determination of a structural form of specific geological objects.
