Single component Distributed mining seismograph Seismic survey recorder Slot wave seismic electrical instrument
Product Description
GD-3C is a new generation of high-precision three-component seismic node instrument launched by our company. It adopts GPS/BDS clock synchronization algorithm, ultra-low power circuit design and real-time data communication technology. The product has high integration, no contacts, long continuous working time, and is suitable for various complex surfaces and harsh environments. It adopts the most advanced analog-to-digital conversion technology, and its dynamic range far exceeds similar products, and it can detect even smaller vibration signals.
External power supply, GPS, communication antenna, etc., can be used for long-term safety monitoring of mines, slopes, glaciers, etc.

Project Development
1.Fracturing monitoring
Microseismic monitoring of hydraulic fracturing in a well:
• Using three-component and single-component nodes for continuous observation, a total of 519 fracturing events were identified. After inverting the source mechanism of the event and interpreting the typical hydraulic fracturing microseismic cracks, the spatial occurrence of the well's fracturing crack direction, inclination, crack length, width, height, etc. was obtained.
2.Active surface waves
Evaluation of tamping effect: The track spacing is 0.5 meters. From the apparent shear wave velocity profile, it can be seen that the speeds of measuring points 5, 9, 35, and 36 are relatively low, and the tamping effect is not ideal, and tamping needs to be strengthened.
3.Short-period dense array
Inversion of 3D S-wave velocity structure based on background noise imaging method.
