Silixa Talks About Benefits of Microseismic Monitoring in Mining Activities

According to the distributed sensing solution provider, microseismic monitoring increases safety through improved interpretation of the data collected, and increases operational efficiency.

Silixa, a global leader in fibre optic-powered data tools, sheds light on the importance of microseismic monitoring in detecting small seismic events to address the uncertainty of subsurface operations.

Being at the forefront of innovation, the company also offers high-end Distributed Acoustic Sensor (DAS) microseismic monitoring.

“Silixa’s DAS microseismic monitoring provides continuous data, processed to contribute information to aid understanding of the geomechanical response to mining activity and of seismic hazards,” explains a spokesperson from Silixa.

Microseismic monitoring helps gain in-depth insight into the distribution of subsurface stress and deformation according to the space-time evolution of fractures and cracks in the rock mass caused by industrial activities.

Compared with conventional 3D seismic systems that estimate acoustic reflections produced by an energy source, microseismic monitoring technology is a passive seismic technique that uses passive sources instead of artificially induced ones.

An advanced technology for seismic observations over a broad range of frequencies, the microseismic technique can be used in tailings dams monitoring, regional seismicity monitoring, hydraulic fracturing, and induced seismicity monitoring.

Besides addressing the potential geological hazards through assessing seismic risks, microseismic monitoring systems also offer a higher degree of accuracy and reliability when it comes to data interpretation, the company says.

On top of this, by integrating the one-cable DAS measurement data with data captured by class-leading DTS (Distributed Temperature Sensor) and DSS (Distributed Strain Sensor) systems, more detailed information about the microseismicity of a target area can be obtained. The results are many: enhanced site safety, remote and optimised operations with no human involvement, minimum maintenance requirement, and more.

In addition to enabling precise processing sequences for enhanced interpretation of the gathered data, the dense spatial sampling with DAS microseismic monitoring bolsters operational efficiency.

For example, built on its years of sensor expertise, Silixa’s low-maintenance DAS microseismic monitoring provides a dense spatial sampling of the wavefield even in the most extreme environments, says the company.

According to Silixa, by using high-end fibre-optic DAS solutions, operators can get high-quality, accurate data, thus driving cost-efficiency.

For example, comprising a class-leading optoelectronics interrogator and sensing cables equipped with highly engineered Constellation fibres, Silixa’s Carina Sensing System offers a broadband response with a noise floor similar to geophones. It means that with this high-end sensing system in place, operators can gain a precise recording of small-scale seismic events over a wide spectrum of magnitude. Plus, operators can gain a spatial sampling of <1m with Carena’s long-range fibre-optic sensing element. This results in a large operational area that can be monitored with a single measurement, which leads to cost savings.

Furthermore, by allowing both permanent and temporary deployment of the fiber-optic cables, DAS microseismic monitoring system can offer a higher level of flexibility.

Plus, these cables can remain fully functioning for years while offering two installation options: borehole installation or buried at the surface.

Founded in 2007, Silixa is an award-winning company helping the mining, alternative energy, oil and gas, infrastructure, and earth and environmental sciences industries efficiently address critical measurement challenges.
