The NSW Department of Primary Industries (DPI) has released a safety alert urging all mines to maintain their elevated work platforms after two workers were injured during routine maintenance work on an underground coal mine.
Both suffered arm injuries (including a fracture) when the work platform they were working on suddenly pivoted upwards, causing them to be jammed between the mine roof and the top of the work platform.
According to the NSW DPI safety alert, the workers were hanging cables to the roof of the mine.
The work platform was attached to the front of a 913 load haul dump (LHD) via a quick detach system (QDS) and was being driven by the LHD operator.
While the LHD was being driven in reverse, one wheel traversed a 300 mm step in the floor, causing the work platform to suddenly pivot upwards and contact the mine roof.
An investigation into the incident revealed that poor roadway conditions made it difficult for the LHD operator to control the speed of movement of the work platform.
The NSW DPI recommended that all mines review their systems of work which require people or materials to be lifted, to ensure they comply with clause 142 of the OHS Regulation 2001.
