SONAR PROBING AS A MINING AND TUNNELING TOOL

The basic aim of this program is to use acoustic probing as a tool to investigate discontinuities in salt. A narrow beam of sound is needed to accomplish this. Although the original approach to obtaining a narrower beam in salt was the standard one of using a large transducer, it was found more effective to use nonlinear acoustics to generate the narrow beam of 24 kHz within the salt itself and use the Sonar II system as a receiver. Now that the nonlinear acoustics method is being used, the research objective changes are outlined. Some results of investigations into nonlinear acoustics are recounted. A mathematical analysis of acoustic scattering from various cylinders is presented. The latest research results in the Grand Saline salt mine are reported.
