A little bit more on the failure of that tailings facility in Brazil from some-one on the ground:

The accident was in a very small mine close to Belo. It was an old tailings dam that was not  supposed to be in operation anymore. But they decide to pile dried tailings on top of it. I don’t have technical details about the failure but I guess it is very similar to a previous one I took you to see. At the moment of the failure, equipment was working at the same point. That’s the reason for the deaths. It is going to take some time for us to get the conclusions about the real cause of the accident. But, as soon as I get some more information I will let you know.

Thanks to this fellow for letting us know.

The five pictures in this posting, were taken (by me) at the Getty Center in Los Angeles.  This place is surely a testament to genius and attention to detail.

Yesterday I was asked if Canadian guidelines are adequate to deal with the Mt Polley situation. More specifically, the questions continued: if the current Canadian guidelines regarding tailings dam safety had been implemented, would the failure have been avoided. Before I answer these questions, let us first take a look at the guidelines that are out there. (more…)

I have not posted on this blog the past few days.  The reason:  I was at a fly-in, fly-out camp where the internet connection is sporadic & they do not make it easy to access spurious blogs.   Plus the weather was terrible:  ice-rain in which planes could not fly. (more…)

Today was a sad day.  The MET opera, watched live in a quiet and safe place, Coquitlam east of Vancouver, BC, was Aida.  Yet the national tragedy of the twenty-eight deaths in Connecticut overshadowed the tragedy of the opera.  (more…)
