At this link is an announcement that the BC regulators are seeking proposals from consultants to help them evaluate the independent dam safety analyses they have ordered be done by independent folk on all the tailings facilities in BC. Dam Safety Inspection Review is the heading.  Here is the full announcement — it is fascinating for what it tells and what it does not tell. (more…)

Just home from a four-week journey that took me to  Peru, Chile, Keystone CO, Banff, and Ekati NWT.  It is good to be back in the house where you can throw off the formalities of travel, eat simple food, and get drunk in private. They say that Peruvian food is the best in the world.  Indeed it is if you are in a fancy, expensive place in Lima.  But go to a mine and eat what the miners eat, and it is terrible beyond belief.  Rice & beans and other unrecognizable substances of gooey texture.  I lost weight.  Maybe it was the altitude = 14,500 ft.  You walk slow and breathe deep in those conditions.

Today’s keynote address was by Tamara Johndrow of Freeport-McMoRan Mining Company. Her topic was FCX Tailings Stewardship Program. Let me note what I recall of her talk. Tamara heads a group of about ten engineers.  Their task is to look after, or steward, all of Freeport-McMoRan’s tailings facilities.  If I recall correctly that includes 18 operating facilities and over fifty closed facilities.  That is a large portfolio. They have a single objective:  NO FAILURES. (more…)

The first day of presentations at the Tailings and Mine Waste 2014 Conference.  Gordon McPhail delivered a talk in honor of Geoff Blight, who passed away earlier this year.  Geoff made so many contributions to tailings that we were talking for at least an hour about him and his genius.  I honor him here in the only way I know:  record my opinion that he was one of the great of tailings.

Mining Travel in Peru

No posts the past few days. I have been travelling in Peru and Chile to remote mines where we work long hours and have intermittent email & internet connections. It has been fun and instructive: to examine the problems that arise on mines far from the center and focus; to see how local consultants devise solutions in climates that differ from those I am used to; and to examine alternative ways of constructing tailings impoundments.  I cannot write of what I have done, for it is all client confidential, so instead here are a few photos take at random along the way. Enjoy.

Woke up late this morning after twelve hours sleep—seems the older I get the more I want to sleep.  Maybe it is old age or maybe riding my bicycle to work tires out the old body.  Or maybe there is something breaking down inside that the doctors cannot discern. (more…)

We have just finished the InfoMine Conference on geosynthetics in mining.  I think it was a success although I had better await the evaluation forms before coming to definitive conclusions. The proceedings will be available through the InfoMine e-Store at this link.  In my opinion, this is a magnificent collection of papers on a topic that has long cried for detailed, focussed attention. For the use of geosynthetics in mining is different to the use of geosynthetics in landfills and other civil engineering application.  The mining projects that involve the use of geosynthetics are orders of magnitude larger than any other category of projects.  The challenges are greater: there are few precedents; there are no substantive regulations; and the consequences of use and misuse are greater.
