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

Threads in flameproof motors - technical paper
The department investigated a failure of screw threads in a flameproof (Ex d) motor and commissioned the Welding Technology Institute of Australia (WTIA) to analyse the failure and give advice on the repair of screw threads in flameproof equipment. This report is provided by the WTIA and supported by the department.
The inspection and repair of screw threads in flameproof equipment is important in maintaining explosion protected properties of flameproof (Ex d) equipment. This technical paper gives advice on the inspection and repair of screw threads in flameproof equipment. Examination and repair of threads in flameproof enclosures
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:
