Uncontrolled movement of longwall transformer cart

What happened?

On 21 December 2023, an underground coal mine longwall transformer cart was being trammed into position when it moved down the grade in an uncontrolled manner for approximately 20 metres until it came to rest against a stationary load haul dump (LHD) machine.

Four coal mine workers (CMWs) were in the vicinity of the longwall transformer cart at the time of the incident. None were in the travel path of the out-of-control cart, however, the potential for a serious incident was evident.
