In an upcoming EduMine course on Risk Assessment, Decision Making, and the Management of Mine Geowaste, we write the following on the topic of Net Present Value (NPV): (more…)

I spent some time last week, this past weekend, and today polishing the webcast coming up next week on Geosynthetics in Mining.  We started out as a small group, Tarik, Terry, and me.  But as we talked and planned, we realized we needed other to augment us.  So I am proud to tell that we now have Abigail, Bertrand, Marat, and Ryan join us.  Here is more detail: (more…)

If you are interested in the use of geosynthetics in mining, or seek to use geosynthetics in mining, or need as a consultant to provide your client with advice on geosynthetics in mining, or you are a manufacturer or supplier of geosynthetics to mines, then you should join us March 10 to 12th on the upcoming EduMine webcast.

Last week I needed to brush up on stability analysis of waste rock dumps or embankments as they are sometimes called.  I went to the obvious sources: EduMine.  I opened the course Design  and Operation of Large Waste Dumps by Tim Eaton and Scott Broughton. In the section on Analysis they present a masterful description of the various failure modes and how to analyse them. They add this on probability of failure: (more…)

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.

EduMine has just posted at this link, a Spanish version of our (Bernard Brixel and my) course Introduction to Groundwater Modelling for Mines & Mining.

The English version has proven popular since it was first posted in 2013.  Now it will be easy for Spanish speakers to also do the course.

I must thank AngloGold Ashanti for sponsoring the translation.  We all owe them a vote of confidence.  For they support continuing education.

This course joins my other, associated course in English and Spanish on Groundwater in Mining.  Translation of that course was sponsored by Goldcorp.  Thanks too to them.

If you do the course, and see room for improvement, please let me know.

And keep in mind the other two courses on EduMine on groundwater modeling:

Groundwater Modeling for Mining 1 – Model Conceptualization.

Groundwater Modeling for Mining 2 –  Numerical Modeling

Bernard and my two courses and their Spanish translations are introductory–they will lead you into the topics so that you can plan, manage, review, and at the first cut, deal with groundwater in mining.  The two noted just above by my colleagues here in Robertson Geoconsultants, are detailed and best tackled once you have some background, knowledge, experience, and practical involvement.

Just seen Minister Bennett say the Mt Polley loaded gun was underground and the trigger was the steep slope.  He could have added that the excess water in the reservoir was the bullet the gun fired.  A better metaphor of the breach than a line of falling dominos. The real question is where do we go from here? (more…)
