It is no secret that I make money off mining. I work as a part-time civil engineer with a consulting practice that works around the world. I retired nearly ten years ago, after nearly ten years working on landfills, California earthquakes, and supporting lawyers representing big companies falling foul of law suites. I have an LLB degree in addition to my civil degrees and was able to use this knowledge to translate technical and engineering issues into winning legal arguments. (more…)

The PowerPoints of presentations from the Tailings and Mine Waste Conference in Keystone are now available. At least the PowerPoints of those authors who gave permission. See this link.
They are all interesting, so choose those that interest you.
I recommend the presentation by Steve Vick who is one of the reviewers of the failure of the Mt Polley tailings facility. He assures me that he compiled the presentation before the failure and there is no connection between what he says in his presentation and what he might say in the panel findings.
The presentation by Franco Oboni touches on the same topics as Vick’s but takes a different approach.
I particularly like the presentation by Craig Benson on the hydrologic performance of final covers. He concludes that we can and have constructed covers to last for at least 1,000 years.
I am sure there is much to say about these presentations and indeed the other presentations, so please comment.

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…)

It does make a difference to your wages if you work on a Canadian metal or diamond or fossil fuel mine. Here are some numbers to highlight the differences. I quote from the new CostMine 2014 Survey Results- Canadian Mine Salaries, Wages and Benefits. Here are some average wages by mined commodity in Canadian dollars per hour. The first number is for metal mines; the second for diamond mines; and the third for fossil fuel mines. (more…)
Subaqueous disposal means placement of tailings into or beneath a water cover. Deposition of tailings into a lake is the most common subaqueous method. In many instances the embankment dam is constructed as a water retaining structure and the impoundment is filled with water into which the tailings are discharged. (more…)
The first official day of conference sessions at the Paste 2014 conference here in Vancouver. Sean Wells, Director of Research for Suncor presented the opening keynote address. I cannot possibly here recount all he said. All I can do is note a few points that he made that stuck with me. In due course, his PowerPoint presentation will be available through InfoMine. Get it and take deep thought over it, for his points are provocative, timely, and scary. He noted that the problems of oil sands tailings management are all about scale. They oil sands produce so much tailings that the shear volumes and areas needed introduce problems not encountered in conventional tailings management. I have heard it said that the two oil sands mines, Suncor and Syncrude, produce more tailings per day than the combined total of all the other mines worldwide. His point is made. (more…)
