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. (more…)

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. (more…)
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.

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…)

On the plane to the site I dipped into Nasim Taleb’s latest book, Antifragile. I read a few chapters and have stowed the book for the return fight. But I picked up enough to know that an antifragile system is one that thrives on change, shock, time, and other perturbing factors. An antifragile system is the opposite of a fragile system that inevitable breaks as a result of time, shock, disturbance, and the propagation of a mere crack. Antifragile system thrive on disorder; fragile systems do not. (more…)
