Here is the link to the new report Lower Athabasca Region Tailings Management Framework for the Mineable Athabasca Oil Sands.  In some fifty pages it sets out a new way of dealings with oil sands tailings.  Lots of detail yet not much detail. The document sets itself these goals: (more…)

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.

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.

I have written extensively in this blog about the Alberta Directive 74. Generally I have been derogatory about the Directive. For example at this link I write the following: (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…)
