Posted in consulting, environmental, Geotechnical, North America, Reclamation, safety, Tailings, Waste Rock, tagged Alaska, closure, EPA, failure, mine, pebble, Tailings on February 25, 2011 | 6 Comments »
A slow morning and an even slower computer that took its sweet time downloading files.

I could not but stop to [...]

I am at that point where I should really commit myself to the trade or back off and go a different direction. I am thinking about an advanced degree/further education but I am not sure on what: Mining engineering, geotechnical engineering [...]
Quicksand Incident Control

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 [...]

More weekend mining musings
Posted in Geotechnical, mining, North America, Oil sands, People, tagged Fort McMurray, mining, Oil sands on March 13, 2010 | 2 Comments »
This week has been in Fort McMurray, the center of the mining industry, if you count by mass of material moved and the value of the companies involved. Much of what I did is confidential and not able to be shared in a blog. But here are a few thoughts prompted by the week’s doings.

Spent today tidying up a new course for EduMine. And listening over and over again to Callas singing Norma—can there possible be a more sublime opera? I already have five courses on EduMine, that site devoted to self-paced learning on topics in mining. They are:
