ALTERNATIVE DISTRIBUTED ACOUSTIC SENSING (DAS) SYSTEM
for real-time monitoring of Tailings Dam stability, by means of the surface deployment of sensitive fiber optics.
NOTE: This tailings dam collapse could have been avoided if the DAS solution had been implemented initially.
DISTRIBUTED ACOUSTINC SENSING FOR TAILINGS DAM MONITORING
BY MEANS OF DEDICATED OPTICAL FIBERS
AN EFFICIENT ALTERNATIVE TO THE USE OF GEOPHONE ARRAYS
Golden Taurus Ingeniería (GTI), in collaboration with the Institute of Mine Seismology (IMS) and Terra15 ( provider of DAS data acquisition hardware for mine monitoring), offers specialised and routine monitoring services for the mining industry, introducing a new class of seismic sensor based on fibre optic detection technology for geophysical, seismological and industrial applications.
The advancement of fiber optic communication systems has facilitated the extension of this technology to distributed sensing applications, notably for high spatial (linear) resolution for seismic and even temperature monitoring.
The advancement of fiber optic communication systems has facilitated the extension of this technology to distributed sensing applications, notably for high spatial (linear) resolution for seismic and even temperature monitoring.
Distributed acoustic sensing (DAS) technology uses optical fibre as its sensing element. With a spatial resolution of less than 1m possible, DAS can achieve superior coverage compared to conventional point sensors.
The development and commercialization of DAS were accelerated by its use in the oil and gas industry during the last decade, where applications range from production flow monitoring, hydraulic fracture monitoring, vertical seismic profiling and monitoring of microseismic events.
Other applications that could benefit from DAS include geophysical imaging for mineral exploration, seismic interferometry as used in tailings dam monitoring and monitoring mining-induced seismicity complimenting conventional arrays.
