A Seismic Communications Investigation Employing a Piezoelectric Transducer
Abstract
The purpose of this effort was to investigate the feasibility of employing a piezoelectric transducer for seismic communications in mine environments. The transducer incorporated a high Q, spring-mass resonator to load the air side of the piezoelectric crystal. The resonant frequency was seismic load dependent and fell in the range of 300 to 340 Hz. The effort included a mathematical analysis of the transducer, with corroborative laboratory tests, together with actual communications experiments performed first in an open-formation limestone quarry and finally in an operating iron mine.
