Seminar: ‘Lessons from Yucca Mountain Standards, Regulations & Performance Assessments

Professor Rodney C. Ewing, Edward H. Kraus Distinguished University Professor
Department of Earth & Environmental Sciences, University of Michigan
‘Lessons from Yucca Mountain Standards, Regulations & Performance Assessments”
Yucca Mountain, Nevada, was scheduled to be a geological repository storage facility for high-level radioactive waste until it was defunded in 2010. This seminar is sponsored by the A. E. Seaman Mineral Museum and hosted by the Department of Geological and Mining Engineering and Sciences. There will be a social after the talk in the Dow sixth-floor atrium (lakeside).
Friday – March 22, 3:00 to 4:00 pm DOW 642; Social to follow in 6th floor atrium, lakeside

GMES Seminar: Cable Shovel Durabaility in Formation-Excavation Engineering

GMES Seminar: Cable Shovel Durability in Formation-Excavation Engineering
Muhammad Azeem Raza, Instructor, GMES, PhD Candidate of Mining Engineering

Cable shovel is a primary excavation unit in many surface mines around the world. The capacities of the shovels have seen an ever increasing trend to achieve the economies of large scale operation. The modern day shovels have 100+ tons per pass production capacities. The dynamic force of 100+ ton material combined with the dynamic cutting, friction and acceleration forces during the excavation result in severe stress loading of the shovel front end components. Stress and fatigue cracks appear, as a result of this cyclic stress loading, resulting in expansive breakdown, reduced efficiency and production loss. Numerical and analytical techniques can be used to model the stress and fatigue failures.
In this seminar we will discuss the challenges and on-going research in cable-shovel formation-excavation and durability studies. The talk will include: (i) kinematic and dynamic modeling of shovel, (ii) stress and fatigue failure modeling (iii) life expectancy of shovel front-end components.

Muhammad Azeem Raza, an instructor for GMES, will be presenting his work titled “Cable Shovel Durabaility in Formation-Excavation Engineering”. Mr. Raza is a PhD candidate for a degree in Mining Engineering at the Missouri University of Science and Technology, Rolla. He is also an assistant professor at the University of Engineering and Technology, Lahore where he taught for three years before coming to the US for his PhD.
