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.

Day one of the  conference Paste 2014.   Actually the actual conference begins tomorrow.  Today there were short courses and meeting of friends and fellow travellers on the mining journey.  The most beautiful was a lovely lady from Brazil who is studying at the university of British Columbia for a semester and will be a mining engineer in a year or two.  We chatted over lunch and if she is, as I believe she will be, the future of mining, the profession is in good and beautiful hands.

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.

The general approach to undertaking a risk assessment is well described in International Standard IEC/ISO 31010, which also provides considerable information about risk assessment methods. It notes, however: “The standard does not provide specific criteria for identifying the need for risk assessment, nor does it specify the type of risk analysis method that is required for a particular application.” (more…)

Most engineers have no idea what the strength of a soil or tailings implies.  Let me write a little about the physicality of soil and tailings of a given strength. (more…)

The promise of results from risk assessments is as seductive as the picture above.  The results are as fuzzy and fantasy-based as the picture above.  But doing risk assessments is as much fun as it would be to be a participant in the scene above.  Let me explain. (more…)

On Tuesday I was in yet another of those asinine arguments about what constitutes “perpetual” in mining and mine closure.  I had heard all the arguments, smart and cynical, more than thirty years ago when we debated them on the UMTRA Project.  But the pusillanimous arguments continue, for everyone has an opinion and wants to be heard.
