Received the following by email. Not sure where it originated, or how widely it has been circulated. All these words remind me of growing up on a mine in South Africa. We used them all in common speech. So sad they cannot now be used by us to color or talk. Still you may enjoy. Sommer so! (more…)

Planning for the upcoming conference Geosynthetics Mining Solutions 2014 is well advanced. As the above news items attest, there is great interest in geosynthetics and this conference will focus on the use of geosynthetics in mining. We have many fine sponsors and a great slate of papers—with more still on their way. Please to be able to tell that Mike O’Kane and his folk at O’Kane Consultants have promised two great papers on the use of geosynthetics in the covers of closed mine waste disposal facilities.

Words cannot capture a day of intense impressions.  Yet let me try. Go east of Lima into the hills (as I did today) and see this:

  • Tailings clinging to the steep hills in defiance of gravity.
  • A mine closed by the government to perfection.  They know what they are doing!
  • Filter-pressed tailings transported fifty kilometers up 1000 m elevation to a new disposal site — economically?

Here is a copy of an email alert that I received today.  All about a new book on gender in mining.  I quote below from the email and from the Amazon.com site where you can buy the book. (more…)

The past week at a mine in Honduras.  Too many impressions to record right now.  So a few photos instead.

The final day of the conference Paste 2014 in Vancouver today.  The keynote was about filter pressed tailings management at Pogo in Alaska.  Too complex to blog about, but worth reading the paper and looking at the PowerPoint presentation when they available on InfoMine. (more…)

More than twenty-five years ago, I spent six months in Oak Ridge, Tennessee opening the Jacobs Engineering office.  Then we won a job that required me to move to Pasadena, California.  This week I am back in the state and see much change.  Highway 40 from Oak Ridge to Knoxville was a quiet road.  Now it is continuous commercial development and an eight-lane freeway.  The weather is still perfect and the people still have that wonderful can-do attitude.

Those miners I have been with this week are so American.  Their attitude is always:  that is a great idea–we can do it; but here is a better idea–what do you think?

So we leapfrog from issue, to question, to idea, to analysis, to solutions.  And the outcome is a positive advance based on mutual agreement.

Did you know that Tennessee is a mining place?  One of the largest producers of zinc concentrate?  Some of the mines are one-hundred and more years old.  Of course there is still some coal mining, but I know little of that.  As the picture above shows, natural gas is a thing I thought not off way back then.

The food is great:  meat and sauces, fries, and sweet tea.  Then there are those many variations of Jack Daniel’s that I cannot get elsewhere.  Right now I type to the tune of Winter Jack: “A seasonal blend of apple cider liqueur & Jack Daniel’s Tennessee whiskey.”  Magnificent.  No wonder mining is so smooth.

I am told the regulators are great people to work with.

So the mines advance with the usual issues to be dealt with: too much vegetation in waterways & spillways; seepage through rock embankments; tailings pools too close to dikes; the threat of hurricane-induced probable maximum precipitation; and the New Madrid earthquake that makes this a region where seismic stability analyses are no deal and a big deal.

The guys from Mining.com told me today that the major news organizations contacted them asking for comments on the recent mining tragedy in Turkey.  The Mining.com guys had no comment.  “What do we know more than they do?  What can we say that adds to insight?” (more…)

I am not a meeting person.  I fall asleep in meetings as the committee queens pontificate.  Worse: I grow irritated as the bobbing heads proffer opinions about things they know nothing about.  Even worse: I get into inane arguments with egos that see this as a contest of gladiators. (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.
