Electrical engineering safety information sheets

Information sheets are aimed primarily at smaller extractive operations (quarries), however they are worthy of consideration by larger mining operations, both coal and metalliferous.

The information sheets are developed by the Inspectors of Electrical Engineering in response to issues identified during mine site electrical engineering safety audits at extractives operations (quarries) and in response to questions asked by operators on how they may better manage electrical engineering safety at their operation. The information should be used as reference material in developing site electrical engineering safety standards.

Operation of remote control loaders in underground  metalliferous mines

Fault trees can be used as part of the mine's risk assessment process for the use of remote control loaders. The fault trees encompass two modes of operation:

  • Tele-remote
  • Line of site.
