Coal Inspectorate | Alert | No.422 V 1 | 12 January 2023

Effective implementation of hazard control for continuous-miner rib-protection system

What happened?

On 27 July 2020 two coal mine workers (CMWs) received serious injuries from rib spall while working on a continuous miner (CM) in an underground development panel heading.

The incident occurred as the CMWs were installing roof support and extending ventilation tubes. An inspection of the site revealed that the machine mounted rib protection system installed on the continuous miner did not provide an effective control for this hazard.

Safety Alert 377 was published on 27 August 2020 soon after the incident occurred, and the Inspectorate commenced a detailed investigation into the incident. The investigation has now been finalised with all factors – including the design, installation and practical application of the engineering controls – being considered. The findings and recommendations from this investigation follow.
