Shear-Wave Seismic Reflection Exploration for Cavities and Tunnels. Volume 1. Study and Design of Techniques

Abstract

A borehole-coupled asymmetrical force transducer operating on the electrical arc discharge principle is recommended as the source device and three-component borehole-coupled seismic detectors are recommended for complete SH-wave data acquisition. This seismic exploration system, designed to operate in the frequency range of 400-1,600 Hz together with specialized data processing techniques capable of preserving the high-frequency timing accuracies in the seismic signals and enhancing reflections from localized cavity targets, is recommended for future prototype development and field evaluation.
