Last night we attended the International Mining magazine’s induction of new members of the Mining Hall of Fame.

It was a grand affair.  Many worthy folk in the mining industry were inducted.  I am told that the March or April issue of the magazine will document their achievements and contributions to mining.

I note only Andy Robertson who was inducted for these contributions:

  • Founding of Steffen Robertson and Kirsten, now SRK.
  • Founding of GemCom that now has the name Geovia.
  • Founding of InfoMine and EduMine, both of which I contribute to.
  • Founding of Robertson Geoconsultants for which I work.
  • Leading the way forward on responsible tailings management.
  • Leading the technology on acid mine drainage.

I might add that it was Andy who got me started on this blog.  Although he has had occasion to rue that lead and the blog, for on a number of occasions he has been asked to tell me to remove postings.  As a true gentleman, he has done so with discretion and dignity.

In his acceptance speech Andy thanked his family, his colleagues, and his clients–all of whom have supported his hard work.  He mentioned only one name:  Professor Jere Jennings who taught so many of us in mining geotechnology the basics of the art.  His contributions and memory live on in people of Andy’s caliber.

Decision making in engineering demands a logical process that is well documented.  Particularly if you are selecting a new site for a mine waste disposal facility.In 1983,  Andy Robertson and I wrote a paper available at this link on site selection.  The ideas were based on what we did to locate the site of the tailings facility for the then new Greens Creek mine.  The site was selected and is still in use.

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…)

I have moved on from countries and companies. I have left (and re-entered) countries. I have left companies and joined the principals in other companies. I have, in a word, moved around. At 67, I spend no time cogitating on these past decisions.  With so long a history of making decisions and moving on, I have so much to regret that I would go crazy thinking what would have been had I not made those many decisions.  It is futile to regret a past decision that may have been the wrong decision.

A picture of a 1,000-year old earthen mound in Central America. 

Goes to prove geotechnical structures can endure stable for at least that long.

Today I explained the differences between Failure Modes and Effects Analyses (FMEA), Value Engineering (VE), Multiple Accounts Analysis (MAA), and Risk Assessment (RA) to some unfamiliar with any of these tools to support engineering judgment as the basis for decision making. In so doing, I had to go back to basics and thus myself uncovered a new and deeper understanding of the basics. (more…)

I learnt today that Geoff Blight has passed away.  I can pay tribute to him best by writing of those times I worked with him. He was a professor at the University of the Witwatersrand.  He came in and took over when Professor Jennings died. I never had a lecture from him, so I leave it to others to record his lecture style and teaching abilities–both of which I was told were superb. (more…)
