ESG provides industry-leading microseismic systems for installation at mining and geotechnical operations around the world. These systems provide a continuous stream of real-time information that help both geotechnical and ground control engineers understand how a site is responding to operations. These complete microseismic systems are easy to use, modular for simple expansion, backwards compatable and operate in a Windows environment.
ESG designs and manufactures all hardware and software in-house, including Paladin® data acquisition units, geophones and accelerometers. This allows ESG to fully customize any microseismic solution to meet specific client needs. ESG does not sell products stand-alone, rather they are manufactured for use as components of complete microseismic systems.
The Paladin® 5 is the latest version of ESG’s next generation digital microseismic recorder. As the backbone of ESG’s microseismic data acquisition system, the Paladin 5 32-bit digital seismic recorder enables accurate detection of a wide range of seismic event magnitudes within a flexible, customizable platform.
Continuous recording on all stations at once ensures that no data is missed. Unique triggering methods can be configured to record event data based on specific criteria.
The Paladin® 5 32-bit digital recorder has all of the same great features as the PIV, with a number of improvements to performance, reduced power consumption and the addition of Bluetooth® capabilities.
Like the PIV, the Paladin® 5 incorporates a removable, licence card that controls the onboard capabilities of the recorder. Similar in functionality to the legacy Paladin Sensor Interface Box (SIB), the license card comes in two forms and is key to unlocking the full power of ESG’s Paladin® 5.
In its basic version, the PIV Daughter Card (PDC) offers a geophone pulse diagnostic test. The more powerful Advanced Diagnostics Board (ADB) introduces a wide range of additional features on the PIV, enabling powerful on-board processing and diagnostics capabilities.
The ADB is designed to interface with both geophones and accelerometers. Lights on the front panel indicate channel performance. Advanced diagnostic tools include voltage measurement, sensor auto detect, programmable AC/DC coupling, auto detect-correct polarity, geophone parameter extraction among other features. Use of the ADB simplifies installation and provides real-time feedback about the health status of the attached sensors.
The Portable Paladin® is a rugged, web enabled, low power digitizer and microseismic recorder. In addition to ESG's suite of geophysial sensors, it is compatible with a variety of broadband and short period seismometers.
The Portable Paladin is equipped with ESG’s Paladin® IV 32-bit digital seismic recorder, but is designed specifically for use in remote locations where data transmission is not feasible. Instead, the Portable Paladin® houses on-board continuous or triggered data storage via USB or compact flash.
The Portable Paladin® is not recommended for extended periods of monitoring in either underground or surface applications. Rather, it is designed for temporary, portable use.
Seismic sensors detect and measure small ground vibrations caused during mining operations. They can be deployed in various configurations around a zone of interest to provide the best possible detection coverage. ESG offers a range of seismic sensors, including geophones and accelerometers for downhole, uphole and surface installation. Sensors are also available in triaxial (3-component) or uniaxial formats for added flexibility.
Geophones are commonly used sensors in mining applications for their robust performance and cost effectiveness. ESG offers two primary types of geophones. Our 15 Hz geophones easily detect signals associated with high frequency, small-scale microseismic events and are omni-directional for installation at any orientation. Our 4.5 Hz geophones are optimized for larger magnitude seismicity (such as blasts or strong-ground motion events) and must be installed vertically.
Accelerometers are often included in sensor arrays for their increased sensitivity and ability to detect small magnitude seismicity. ESG offers a range of omni-directional accelerometers with sensitivities of 0.1 V/g, 1 v/g, 2.4 V/g and 30 V/g.
ESG routinely designs microseismic sensor arrays that use a combination of geophones and accelerometers for optimal array performance. Please contact ESG if you are interested in discussing available options or to request detailed product specifications.
ESG’s Windows-based Hyperion Seismic Software (HSS) Suite has been designed with the end-user in mind. Retaining powerful functionality in a stream-lined environment, the HSS provides a faster and more user-friendly platform for processing and visualization than other software on the market.
ESG's HSS suite is available to mining operators as a component of our complete microseismic solution. As such, it is not available as a stand-alone software platform. The HSS suite comprises a number of core software modules including:
ESG’s Paladin data acquisition systems convert seismic data from hardware devices (i.e. geophones and accelerometers) into digital signals. These digital signals are then monitored by the Hyperion Network Acquisition System (HNAS™) software. Data may be recorded in continuous streams or as discrete "triggered" events before being permanently stored on an acquisition computer.
WaveVis is used to visualize and process full waveforms captured by ESG's microseismic system. First-arrivals of P-waves and S-waves are identified and used to determine event source location and various source parameters such as event magnitude.
SeisVis allows for advanced 3D-visualization and interpretation of site seismicity using event information and scaled site geometries. Event locations, magnitudes, and site velocity profiles among other parameters, can be viewed with respect to site geometry or models using a variety of display options.
Seismicity can be viewed for specific events, or animated over an extended time period using the VCR playback option. Observe changes in site conditions over time to visualize site seismicity or identify and manage potentially hazardous conditions.
