SEISMIC DETERMINATION OF GEOLOGICAL DISCONTINUITIES OF RAPID EXCAVATION

A STUDY OF THE FEASIBILITY OF USING ACOUSTIC SIGNALS TO DETECT DISCONTINUITIES AHEAD OF EXCAVATION HAS SHOWN THAT REFLECTING INTERFACES IN A HOMOGENEOUS ROCK CAN BE EASILY IDENTIFIED. MOREOVER, DISCONTINUITY INTERFACES IN A VERY COMPLEX FIELD SITE (WHERE THE ROCK FACE WAS WEATHERED, WAS FULL OF JOINTED ROCKS, AND HAD A DISTRESSEED ZONE RUNNING ALONG MINE WALLS) COULD BE IDENTIFIED WITH A REASONABLE LEVEL OF CONFIDENCE, USING A CROSS-CORRELATION TECHNIQUE FOR SIGNAL PROCESSING. /AUTHOR/
