Rajant and ESG Solutions Announce Strategic Partnership for Carrying Microseismic Data to Surface for Underground Mining

Rajant Corporation, the provider of Kinetic Mesh® wireless networks, and ESG Solutions, an industry-leading microseismic solutions provider for the oil and gas, mining, and geotechnical industries, have completed successful testing with Rajant as the backbone for carrying microseismic data to the surface. Underground and open-pit mining customers will benefit as both companies start deployment trials in October as the last step in the qualification process.

“Many mines install microseismic systems for rockburst monitoring and to collect data from microseismic events that can lead to a better understanding of rock mass deformation. ESG Solutions installs microseismic systems that rely on sensors (geophones and/or accelerometers) to record digitized seismic waveforms with our ESG Paladin® data acquisition units housed in junction boxes. Each Paladin® unit must be accurately time-synchronized across the network for optimum seismic event location determination. Data and system timing signals are currently transmitted to and from the Paladin units via fiber-optic networks. To reduce initial system costs and ongoing fiber system maintenance, clients have been asking if it would be possible for our systems to operate on a wireless system”, shares ESG’s Technical Sales Advisor Tony Butler. “The main hurdle to a wireless approach for microseismic monitoring has been the ability to provide accurate seismic system timing synchronization between the Paladin units. With Rajant Kinetic Mesh, we are overcoming the time synchronization issue with Precision Timing Protocol (PTP) system timing of 30 microseconds (+/- 10 microseconds) being achieved for networked Paladins. Together, we have demonstrated in the lab that Rajant and ESG can do seven hops through the Kinetic Mesh and maintain extremely accurate system timing. This development will allow Rajant’s wireless network to be considered for microseismic system monitoring in the field for up to 10 kHz sampling rates. This system timing accuracy is more than sufficient for the vast majority of microseismic systems installed that use geophones and/or accelerometers.”
