ESG’s microseismic monitoring systems can be custom fit into any underground or open-pit mine.

An array of triaxial seismic sensors (geophones or accelerometers or both) are installed underground and/or on the surface to detect and measure the microseismic events associated with regional (natural) or mining (induced) stresses that are occurring within the mine.

The detected seismic signals are transmitted through copper cabling from the sensors to ESG’s Paladin Seismic Recorders, a 24-bit digital acquisition unit which includes pre-amplification and A/D conversion. Each Paladin unit is web-enabled device, with its own IP address (for remote access/calibration) and is capable of providing continuous and/or trigger-based data acquisition.

Once the signal has been acquired and digitized by the Paladin, it is transmitted via Ethernet cable or wireless radio telemetry (for surface based units) to a centrally located acquisition computer. ESG’s Hyperion Seismic Software automatically locates and maps the seismic events in real-time, providing an interactive 3D visualization of source parameters (i.e. magnitude and event location) within the mine. A suite of processing and reporting tools can be used to help determine blast re-entry protocols and identify faults or regions of instability.
