The lecture will be given prior to the Alumni dinner and will address the topic: Regional stability of underground mines – a core risk.

“The history of soft and hard rock underground mining is blemished with regional instabilities of mine workings,” Galvin said. “They can take a number of forms ranging from insidious creep and gradual closure of sections of a mine through to the sudden and unexpected collapse of a whole mine. Regional instabilities still occur on a regular basis throughout the world. Australia has it fair share. As such, they have a significant effect on the quadruple bottom line of business – safety, environment, community acceptance and economics.”

He said that most of the rock mechanics principles which determine regional behaviour of underground workings have been reasonably well established as a result of enquiries into these types of events. This left the question of why regional collapses of underground mine workings continue to occur and their future prevention.
