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…)

I have written extensively in this blog about the Alberta Directive 74. Generally I have been derogatory about the Directive. For example at this link I write the following: (more…)

To end the week, here are a few unrelated postings on the web about things mining. At this link, David Stockman of North American Business Development gives an interview on the topic Dry Tailings Stack vs Wet Tailings Pond.  Make sure to click on the rather obscure play buttons to hear him tell how Mt Polley could have been avoided had it been a dry stack and not a wet pond. At this link is a video showing Pascal Saunier and family singing.  Pascal is of Draintube fame and was one of the presenters at this week’s conference on Geosynthetics in Mining. At this link, available for download is RepRisk’s report on the Ten Most Controversial Mining Projects.  Mt Polley and Obed Mountain of Canada are included.  Here is what they say of Obed Mountain in case you forgot about this one: (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.

A few notes on things heard recently about Mt Polley.  I was told this is all public knowledge, although I have not read any of it on the web. (more…)

I write this fifty percent in jest, fifty percent in earnest, fifty percent with tounge in cheek, and fifty percent as a concerned citizen.  You decide which is which in what follows, for I cannot decide.  After the failure of the Bafokeng tailings facility, we built a dike across the failed area and picked up the tailings on the mine property.  We put these picked-up tailings back in the slimes dam.  Then we built a rockfill dike with an upstream filter across the valley just at the edge of the mine property.  Thus any tailings we did not pick up were washed down to the dike and were in due course picked up and put back in the slimes dam.  In due course, they filled in the failure volume with new tailings as the mine continued production.

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.
