Challenge

Capture and assess the impact of blast-induced ground vibrations and overpressure on nearby infrastructure and residential buildings, while at the same time enabling operators to optimize blasting processes without compromising community safety.

Solution

The system was installed across six distributed locations, each equipped with an xCAS acquisition unit as part of the Sentry platform. The configuration included:

  • xRover analog multichannel central acquisition with digitizer.
  • D-Series analog triaxial accelerometers for ground vibration monitoring.
  • Displacement transducers for tracking cracking and structural deformation.
  • Environmental sensors for air temperature and humidity.
  • Air-blast microphones to capture overpressure effects from explosions.
  • xPlorer Premium with Voyager software as the central acquisition and data management unit.
  • Observer software suite for advanced analysis, applying Operational Modal Analysis (OMA) to extract modal properties such as natural frequencies, damping ratios, and mode shapes.

All data was synchronized, archived in an SQL database, and made available through a web-based reporting system, ensuring continuous access for both operators and stakeholders.

Outcomes

The system provides reliable insights into the influence of blasting activities on surrounding residential buildings and infrastructure. Real-time monitoring ensures early detection of risks, while automated reporting facilitates regulatory compliance and transparent communication with local communities. In addition to safety, the data helps optimize blasting sequences by correlating ground vibration and air-blast effects with process efficiency—achieving a balance between operational productivity and community protection.
