Profile

Mark Diederichs began his career with a BASc in Geological Engineering at the University of Toronto. After obtaining his Masters degree in Rock Engineering at UofT, his early work involved the development of geological engineering software to aid in underground mining and tunnelling as well as slope stability. He moved on to a position as field microseismic engineer at Creighton Mine, in support of a Queen’s University R&D initiative,  before taking a rock mechanics research position with the Geomechanics Research Centre in Laurentian University where he worked on establishing guidelines fo ground support design  and pursued research related to rockbursts in deep mining. In addition, he has worked as a mining and tunnelling consultant for many years. After completing his PhD in 2000, he joined Queen’s Geological Science and Geological Engineering in 2001.

He specializes in underground rock mechanics issues including damage zone development around tunnels, engineering rock characterization in heterogeneous conditions, support design issues, tunnel excavation challenges in hard brittle rock, soft squeezing ground and, brittle fracture and rockbursting and long term stability of caverns and shafts related to nuclear waste repositories..
