The snow blanketed us today as the Denver Society of Mining Engineers convention begun. Yet it is warm enough to walk through the snow in shirt sleeves. Typical Denver in winter/spring. Yesterday I attended the short course on Seismic Engineering for Tailings Dams. It was well-attended and featured magnificent speakers who brought us up-to-date with current practice in predicting earthquakes and analyzing their impact on mine tailings dams. Of course there was discussion of predicting the maximum credible earthquake, which Jonathan Bray says we are doing it wrong. Contact me if you want the details. (more…)

This picture and the others in this posting were taken by me at Knotsberry Farm in California.
A great place to visit and enjoy a terrifying ride along the raging river of insanity.
If you seek a thorough and intelligent analysis of dealing with uranium mill sites (and particularly the tailings facility) take a look at the following–it is an amazingly comprehensive document–and should be required reading for all involved in mine management, regardless of whether the mine is uranium, copper, gold, or something else.

Just home from a four-week journey that took me to Peru, Chile, Keystone CO, Banff, and Ekati NWT. It is good to be back in the house where you can throw off the formalities of travel, eat simple food, and get drunk in private. They say that Peruvian food is the best in the world. Indeed it is if you are in a fancy, expensive place in Lima. But go to a mine and eat what the miners eat, and it is terrible beyond belief. Rice & beans and other unrecognizable substances of gooey texture. I lost weight. Maybe it was the altitude = 14,500 ft. You walk slow and breathe deep in those conditions. (more…)
The final keynote speech at the conference on Tailings and Mine Waste was from Craig Benson. He talked about mine waste facility covers. He has promised me a pdf of his talk. But in the meantime there are many documents by him and his coworkers readily available on the web that deal with much the same material as was in his presentation. (more…)
A beautiful sunny day in Keystone in the Colorado Rockies and the first day of the conference on Tailings and Mine Waste 2014. Today was short-course Sunday. With Franco Oboni and Cesar Oboni of Riskope, I presented a one-day course on Risk Assessment and Decision Making for Tailings Facilities. (more…)
I have no data to support the opinions I write of in this posting. So please do your own research before deciding, panicking, or acting on anything said below. Today I was outside smoking in the damp rain when my smoking companion said that he had just surveyed the salaries of mining geoscientists (geologists and geotechnical engineers). He noted that it appears that salaries for such folk are, on average, higher in Canada than in the USA. (more…)
