Blast monitoring

Blast monitoring is performed primarily to improve blasting efficiency and comply with government regulations; therefore, a robust and reliable monitor is integral to 100% data capture and results being available immediately after a blast event.

Our systems are designed to relieve personnel of the day-to-day tasks involved in blast monitoring. With a “set and forget” approach, once the unit is placed in the field and switched on, data is sent via either GPRS or Next G communication to a central server where it’s uploaded to the website and sent to users via SMS and/or email.

Timely access to data allows customers to assess if exceedence levels have been breached or perform test triggers to check conditions before proceeding with a blast.



  • No user setup required
  • Fully integrated system - ability to trigger all units from one event
  • 100% blast capture
  • Six weeks data storage
  • Results available via SMS and/or email within minutes of the blast
  • Blast results can be downloaded from the website for further processing
  • Results only available to authorised users
  • No minimum downtime between capture events
  • Dynamic Triggering program.

Event capture

Dynamates® have a program built into their software called Dynamic Triggering.  This program allows one or more Early Warning Units (EWUs) to be identified by the user, usually those closest to the blast epicentre, to act as the trigger source for the other units. 

When a shot is fired the EWU communicates with other Dynamates® within the network and, based on their GPS location in relation to the EWU, each Dynamate® calculates the exact arrival time of the airblast and ground vibration. This time is then captured and transmitted to a central server which uploads the events to a website. The Dynamic Triggering system also determines whether the detected vibration and airblast are a result of a shot fired within your workspace, hence avoiding false triggers caused by other blasts nearby.

We supply, install, operate and maintain all equipment, and capture, verify and report all blast data.  Consequently site maintenance and operation time is significantly reduced.


Blasting activities often produce gaseous fumes, particularly Carbon Monoxide (CO) and Oxides of Nitrogen (NOX). In open pit blasting these gas fumes often dilute into the ambient air and are not harmful however there have been cases of CO being trapped in underground enclosed spaces. Wind then blows fumes into nearby communities and causes respiratory problems and air pollution in the atmosphere.

ECOTECH provide a comprehensive gas emissions plan which can be integrated with both blast/vibration monitoring and dust monitoring programs.
