Last week I needed to brush up on stability analysis of waste rock dumps or embankments as they are sometimes called.  I went to the obvious sources: EduMine.  I opened the course Design  and Operation of Large Waste Dumps by Tim Eaton and Scott Broughton. In the section on Analysis they present a masterful description of the various failure modes and how to analyse them. They add this on probability of failure: (more…)
