Dangerous incident | IncNot0038655

Underground coal mine
Summary: A worker sustained a head injury during a conveyor belt extension in an underground coal mine. Slack cable was being moved inbye on the primary monorail system (from transformer to DMU), outbye of the DMU monorail tow arm.
The worker was found by other workers in a hunched over position and semi-conscious. It is suspected that he was hit in the back of the head, as he could not recall what had happened.
An inspection of the site showed interaction between the monorail cables, hoses and a structure stored on the ground. The cables were tangled around the structure and the structure had moved from where it had been stored.
Comments to industry:  Mine operators should develop a risk mitigation strategy for the task of conveyor belt extensions. Consider engineering controls such as ensuring monorail loops are raised in the area between the DMU pull arm and the boot end. Ensure exclusion zones are in place. Mine operators should also have a standard procedure for managing workers with head injuries affecting their level of consciousness.

Coal processing
Summary: A major slump occurred on a coal stockpile. The slump migrated to three coal train wagons that were being loaded by manned front-end loaders. Coal slurry also flowed through to the rail tracks of several other wagons. A manned front-end loader was close to the failed stockpile. No workers were on foot in the area at the time.
Comments to industry: Mine operators should review their stockpile management documents and procedures and include:
  • design of the stockpiles 
  • surface profile of the stockpiles to manage water at various stages of the formation of the stockpile 
  • controls to prevent water accumulation on the surfaces 
  • measurement of stockpile water levels at various stages of stockpile formation 
  • TARPs for stockpile management to include references to water content in the stockpiles and rainfall events.

Dangerous incident | IncNot0038684

Coal processing
Summary: The tripper on a gantry conveyor inadvertently moved about 20 metres causing the front bogies to de-rail. There was an operator on the tripper at the head chute at the time. The operator was uninjured. The gantry conveyor belt wasn't tracking properly, and operators were attempting to realign the belt. Due to damage to a mile post limit supply cable, the belt was run with the mile marker disconnected at the switch. It appears that the belt was caught up and dragged the tripper along, rather than the tripper moving by itself.
Comments to industry: This incident is under investigation. Further information may be published at a later date.

*While the majority of incidents are reported and recorded within a week of the event, some are notified outside this time period. The incidents in this report therefore have not necessarily occurred in a one week period. All newly recorded incidents, whatever the incident date, are reviewed by the Chief Inspector and senior staff each week and summarised in this report.
