EMS Bruel & Kjaer reveals new solution to mine blast over-pressure

Published by , Editor
Global Mining Review,

Excessive blast over-pressure 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, EMS Brüel & Kjær has announced the addition of a blast overpressure microphone to its vibration monitoring terminal (VMT). The VMT is the company’s innovative and versatile solution for monitoring ground vibration. Now with the microphone, it provides a complete blast monitoring solution.

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 over-pressure microphone gives mine staff and noise and vibration consultants a full record of compliance to optimise operations and to use when responding to complaints.
