Would you like to know more about blast you have experienced?
Ballarat Gold Mine has a network of five permanent and three “roaming” monitors measuring vibrations produced by underground blasting.
Vibration monitors continuously record background vibration until they are triggered by a blast. The blast event, usually lasting between 3-8 seconds, is logged on the device for later analysis. The secure device calculates for each blast a value called the Peak Particle Velocity (PPV). This value is used for compliance. It is chosen because it is a good indicator of disturbance and property damage.
An event report can be generated for each blast. The report will include detailed information about the blast, including: the time it occurred, PPV, duration, and the displacement and frequency of each blast component.
