Yallourn East Field Mine is an open-cut brown coal mine in the Latrobe Valley. A failure occurred when a large block of coal slid horizontally across the mine floor and extended to the Latrobe River diverting it into the mine. No lives were lost; however, there was a 17 per cent loss of Victorian power generation for several months.
PSM’s mining advisor Tim Sullivan was appointed Mining Warden in the State of Victoria to undertake an inquiry into the failure. The inquiry was to establish the facts and circumstances surrounding the collapse, consider safety issues and make recommendations to prevent or minimise the risk of similar future events.
The high-profile collapse attracted significant media interest and public scrutiny. Yallourn power station, which supplied 20 per cent of Victoria’s electricity had to shut most of its generators while emergency repairs were completed.
Technical and engineering opportunities included:
PSM’s rigorous approach included:
PSM successfully provided an unbiased examination by providing extensive mining geotechnical expertise to interpret the practices used to manage and control mining risk at Yallourn before the failure. The Victorian Government accepted inquiry recommendations in full. The inquiry led to the establishment of the Technical Review Board (TRB) and set new standards in industry practices.
