Noise, blast vibration and blast overpressure are significant environmental aspects to be managed by KCGM.

Through the historical development of Kalgoorlie-Boulder, residential areas became established near the operations preceding KCGM. Just prior to the formation of KCGM, six underground mines on the Golden Mile operated "around the clock". The noise environment changed with the change of mining method to open pit operations.

In November 1992 Ministerial Conditions set noise-level standards for the KCGM Fimiston Open Pit operation including general noise levels and air-blast overpressure standards. In 1993 following extensive study and discussion, KCGM established noise, vibration and overpressure monitoring and management programs for the Fimiston operation.

Blast vibration and seismic monitoring sites have also been established by KCGM for the Mt Charlotte operations. Data from these programs are reported to management routinely to enable a pro-active approach and ensure that potential issues are effectively managed.
