Seismographs measure ground vibration and airblast, providing your mine or blasting operation with key data. Vibration data shows how efficiently explosive energy is confined and used to break rock. Your engineering team can use this data to demonstrate regulatory compliance and maintain trust with surrounding communities.
ERG Industrial supplies field-proven seismographs built to withstand the rigours of life on a working mine site. Browse the range below, or get in touch and we’ll help you match the right unit to your site and monitoring requirements.
Record vibration and airblast data in accordance with industry standards and provide proof of compliance for every blast.
Monitor levels near buildings and infrastructure to act before damage thresholds are reached.
Objective data maintains relationships with surrounding communities, verifies that blasts stay within noise and vibration limits, and flags when designs need adjustments.
Vibration readings reveal how efficiently explosive energy is confined and used to break rock, data your team can use to refine blast designs.
Weather-resistant seismographs keep recording under harsh blasting conditions.
Time-stamped event records provide the evidence to defend against damage claims and support independent expert review.
