Case Study/Coal Mine Case Study | Shanxi, China

Aug 18,2026

Using our GN309 microtremor system, the ESPAC method was applied for coal seam goaf detection at the Mazita wind shaft project.
✅ The results show a 90% consistency between microtremor interpretation and borehole verification, accurately identifying the goaf and solid coal boundaries.
🌤️ This case demonstrates how our advanced passive seismic technology supports safe mining operations and geotechnical stability evaluation.
