Vibration, Air-overpressure and Noise Monitoring

Blast Log provides a range of monitoring services that can aid in further understanding and solving vibration and air overpressure problems associated with quarry blasting.

Our monitoring services can work in conjunction with consultancy services including blasting related environmental impact assessments. Click here for more information on our consultancy services.

Vibration & air overpressure monitoring

Monitoring for vibration and air overpressure (air blast) is one of our key areas of expertise.

White Seismograph

We have offered our monitoring services to the following sectors:

  • Quarrying and mining
  • Demolition
  • Property & construction
  • Recycling
  • The public sector

We use a range of commercial seismographs manufactured by White Seismographs and Instantel. All our commercial units meet performance standard as set by the International Society of Explosive Engineers (ISEE).

For more specialised monitoring, we also manufacture, install and operate bespoke vibration monitoring systems that can monitor at up to 5 locations over a 50m distance on a common time base.

These have previously been deployed:

  • on quarry benches to collect more results from a given blast that were subsequently used for scaled distance regression modelling
  • within properties to record blast vibrations in multiple rooms
  • to carry out 'drop heel' floor tests within buildings to determine resonant frequencies

Noise monitoring

Blast Log Ltd Noise Monitoring

We offer a one-off environmental noise monitoring service.

Our Larson Davis equipment is a combination Type 1 precision integrating sound level meter (slm) and a statistical data logger that exceeds all worldwide accuracy requirements for the measurement of noise.

We have provided our noise monitoring equipment for the following:

  • Environmental noise impact assessments
  • Demolition works
  • Traffic noise
