“The Conference continues with the focus of providing a technical forum for the interchange of experiences and new developments in the Australian underground coal industry – particularly longwalls,” organisers said.
The 2-day program covers geotechnical engineering, ventilation and spontaneous combustion, mines rescue, and subsidence.
