Noise and Vibration KCGM

KCGM monitors ground vibration due to blasting at six reference locations between the Fimiston Open Pit and Kalgoorlie-Boulder and at eight locations around Mt Charlotte Underground Mine. Vibration caused by a blast is recorded when ground vibration exceeds the set trigger level of 0.2 mm/sec, and is referred to as a blast “trigger event”.
