Russian Researchers Develop System to Detect Hazardous Underground Vibrations Before Buildings Crack
Researchers from the HSE University and the Institute of Comprehensive Exploitation of Mineral Resources of the Russian Academy of Sciences have developed a real-time monitoring system that identifies hazardous underground vibration sources near mines and quarries before they can damage buildings, roads, and infrastructure.
The technology combines a mathematical model with compact sensor arrays built from several low-cost detectors. By comparing signals from the sensors, the system accurately pinpoints the source of underground vibrations. The margin of error is no more than 7% near the source and falls to 4% at greater distances, while maintaining its accuracy even in the presence of strong background interference.
The sensor arrays can be installed directly next to residential buildings and roads, reducing installation and maintenance costs. The technology also avoids the need for complex data processing methods, making it easier to deploy across a wide range of industrial applications.
