Blasting risk

Blast monitoring in mining is an important tool to measure your impact on surrounding structures and impact on nearby communities when it comes to compliance reporting.

Excessive blast overpressure from mining activity or demolition can cause damage to nearby structures as well as complaints from the community. As a result, blasting can only take place under specific weather conditions and is subject to compliance limits.

To help manage this, environmental management solutions provider, EMS Brüel & Kjær, has added a blast overpressure microphone to its Vibration Monitoring Terminal (VMT). The VMT is our innovative and versatile solution for monitoring ground vibration. Now with the microphone, it provides a complete blast monitoring solution.

Undertaking continuous vibration monitoring enables you to confidently analyse your impact and avoid issues with the local community.  The portable vibration monitoring terminal and web-based software system also helps to save time by remotely accessing real-time and historical vibration levels.

The VMT fully meets the requirements of the International Society of Explosive Engineers, ISEE 2017 for ground vibration and blast overpressure monitoring. It can be used in either a permanent installation or as a portable solution. Units work standalone or as part of a multi-location noise and vibration monitoring network with EMS’ Sentinel compliance service.

Using the VMT and blast overpressure microphone gives mine staff and noise and vibration consultants a full record of compliance to optimize operations and to use when responding to complaints.
