Advantages of a DAS seismic sensor array over conventional geophones for surface and borehole applications:
Distributed acoustic sensing for geophysical and geotechnical applications offers multiple advantages over conventional geophone acquisitions. The increased seismic sensor density combined with the broad acoustic sensitivity and relative low-cost per sensor means affordable high-resolution surveys are now a reality.
The patented design of the Treble DAS interrogators provide users with ultimate flexibility and sensitivity for these applications. Configurable acquisition parameters, dense channel spacing, unmatched high frequency sensitivity for resolving shallow structures, and native save formats that increase sensitivity to broad side wave arrivals. These are some of the features that make Trebles the leading interrogators for near-surface geophysics.
Minesites are often harsh environments that produce large amounts of vibrations which translate to strong ground motion. These vibration sources are plentiful and intense, but more importantly they help with the characterisation of the surrounding rock-mass.
