Lecture: "Investigation of a complex rock slope displacement at Brenda Mines"

Summary: The history and analysis of a structurally complex open-pit rock slope displacement are described. The failure involved part of the only haulage access to a major ore zone. The ongoing movement was monitored using an electronic distance-measuring device and a continuous electronic system specifically designed for the problem. A major fault, infilled with a thick clay gouge, and intersected by other structural features, resulted in the transfer of weight to a rock mass acting as a buttress in the lower regions. Movements were affected by blasting vibrations and ground-water conditions. Remedial measures included limiting blasting levels and lowering the water table, following which mining was successfully resumed in the area.

Born in Springhill NS, he served 5 years in the Canadian Army prior to entering St. Francis Xavier University in 1958. In 1963 he graduated from NSTC (now Dalhousie University) with a degree in Mining Engineering, and joined the Iron Ore Company of Canada in Labrador City, becoming Mine Superintendent two years later.

Peter attended McGill University after being awarded a Canadian Mineral Industry Foundation Scholarship and received a Post Graduate Diploma prior to attending Queen’s University where he received M.Sc. and Ph.D. degrees in Mining Engineering. He joined the faculty of the Queen’s Mining Engineering Department in 1970 and was Head of that department from 1980 to 1990. Upon retiring as a regular faculty member in 1997, he was honoured by being designated as a Queen’s Emeritus Professor. At the Pontifica Universidad Catolica de Chile from 1997 to 2001, he served as the first Canadian Mining Chair, and Full Professor within the Faculty of Engineering’s Mining Department.
