A casual conversation in the parking garage involved this question: “What are the five tailings failures that set the course of history?” (more…)

This week, EduMine posted a new course that I wrote. As is the title of this posting, the new course is called Geotechnical Engineering for Mine GeoWaste Facilities.
I was prompted to write the course when I was called on to explain to a client who is not a geotechnical engineer what is involved in geotechnical engineering. This client was in charge of the design and construction of a large tailings impoundment that involves nearly every aspect of geotechnical engineering. He asked me fundamental questions that demanded a wider knowledge base than a simple answer could provide. Thus I wrote a few short pieces for him and then more short pieces to expand on topics. Eventually it was obvious we needed a complete course. So I wrote it.
The course covers pretty much the complete spectrum of geotechnical engineering as applicable to mine tailings impoundments, waste rock dumps, and heap leach pads. I write from my own experience, including over forty years as a consultant to the mining industry. During that time I have been lucky enough to work on the geotechnical engineering aspects of all these large structures that I collectively refer to as Mine GeoWaste Facilities.
I contemplated a course on tailings impoundments alone. But the topic seemed insurmountable. Apart from that, there is so much written and readily available about the fundamentals of tailings impoundments that I could not face going into competition with so many excellent texts. Moreover, it was clear from interaction with my client that a more fundamental look at the basics was needed. Thus in the course I go back to the fundamentals of soil mechanics that underlie every tailings storage facility, every waste rock dump, and every heap leach pad.
If the topic interests you, I recommend going to the links I provide above, join EduMine, and read the course. Please tell me how you fare and help me add to future updates of the course by telling me your stories. Thanks
