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.

Spent today stuffing the bags to be handed to the over 150 delegates to next week’s conference here in Vancouver on Geosynthetics Mining Solutions 2014.   I also went through the volume of proceedings.  We have some amazingly interesting papers on aspects of geosynthetics use in mining new to me.  There is still time to join us on Tuesday if you push hard.

The exterior surface of most tailings, waste rock, and heap leach facilities include:

  • A top deck which is the flatter surface that forms the top surface of the facility. This is usually sloped at between one and five percent, primarily to promote runoff.
  • The sideslopes which are easily covered if they are inclined at about five horizontal to one vertical (5H:1V) but which in practice may be as steep as 1.4H:1V.

Covers on the top deck are less subject to erosion, slope instability, and soil creep than covers on sideslopes. Thus different covers may be appropriate at the same facility on the top deck as compared to the sideslopes.  Here are a few idle thoughts on sideslope covers for mine waste facilities. (more…)

In selecting topics to blog about, my first choice is something that struck me today as new and interesting.  Today the most fascinating new thing I learnt resulted from a visit by a young Irishman from Nuna Innovation Inc.  He told me about a geosynthetics that I had not hitherto been aware of.

It is snowing in Vancouver.  Nothing sticking to the roads, but the trees are white and beautiful.  Nothing much to do outside or inside for that matter, so just  a few thoughts on mine waste disposal facility covers.

Slimes & Cement

The best cover is no cover.  If you can use the upper tailings or waste rock as the as the growth medium in which a stand of climax vegetation will flourish, you have the best cover. (more…)

I have been much involved in the planning, marketing, and selling of the InfoMine conference Geosynthetic Mining Solutions 2014 to be held in Vancouver from the 8th to the 11th September 2014. (more…)
