The locations of five permanent vibration monitors are marked on the map below. The underground workings are separated by faults into compartments. A plan and cross sectional view of the mine illustrates the location of these faults and compartments. Each stope firing occurs in an area underground defined by the compartment and the depth.

SOV = Sovereign Hill
McK = McKee St
BAR = Barkly St
GP = Golden Point

Ballarat Gold Mine’s vibration limits are set, enforced and audited by the Earth Resources Regulator.
The following limits are approved in the Ballarat Gold Mine’s Work Plan:
