TGMS General Meeting

FOR: TGMS Members and open to the public!

GUEST SPEAKER: Brad Ross, PhD. PE-- Professor of Practice and Assistant Director for the Institute of Mineral Resources at the University of Arizona.  He has over 40 years’ experience in the mining industry and was fortunate to work for some of the largest copper, uranium and coal mines in the world, - helping to solve difficult problems and mentor outstanding individuals.  Although he has worked in a number of locations and positions, the most difficult and challenging job was in 2013 when Rio Tinto sent him in to the historic Bingham Canyon Mine near Salt Lake City, Utah to help prepare for and recover from the largest mining highwall failure in history – the massive Manefay Slide.  Brad has since written a book called “Rise to the Occasion – Lessons from the Bingham Canyon Manefay Slide”.

LECTURE TITLE: "The Massive Manefay Slide" -- The Manefay slide was by far the largest in mining history.  Over 144 million tons of rock and debris burst out of the wall of the mine and traveled over 1 ½ miles in approximately 90 seconds.  Anything in the path of the landslide, such as large mining shovels and trucks, were either destroyed or simply shoved out of the way.  This talk will describe what happened and why.  It will also discuss how the mine was able to predict the failure before it happened to keep everyone safe and then recover from this massive event when most people thought the mine would never operate again. 

Refreshments served.
