Geosynthetics have been used in constructing covers and access roads over soft tailings at the Cannon Mine, Wenatchee, at impoundments at Wismut, and most recently at Pond 5 at the Suncor oil sands tailings mine in Alberta.  We are currently evaluating similar technical procedures for a mine in Chile where we will build access roads over the soft tailings to enable big rigs to go to install deep wells to recover groundwater from beneath the impoundment to augment water supplies in a desert.  (more…)

The Second International Oil Sands Tailings conference is underway in Edmonton, Alberta.  Here is my summary of two days of listening to presentations. (more…)

These past two days we have been in sunny Vail, Colorado at the conference on tailings and mine waste.  Sadly you will have to buy the volume from the organizers to read the papers.  With a bit of patience, we will post some of the presentations on InfoMine in the near future.  Meanwhile let us urge the authors to update their papers on the basis of new ideas gained here at the conference and hence paste their papers on their websites so that we may all more freely share in the information and lessons learnt.   (more…)

    Nordie Morgenstern is well known to all who work in the oil sands tailings industry.  He sits on the geotechnical peer review boards of both Syncrude and Suncor.  He travels the world consulting to mines on geotechnical issues.  He is in great demand as an expert witness on legal cases.  (more…)

   It has been a good weekend, although some mining issues have caused me concern—not enough to induce worry, but enough to merit record in this posting.  Thus let us go through the main events of the weekend and follow the concerns that arise in the course of weekend pleasure.

On Saturday night, we went to see the Marriage of Figaro, put on by the Vancouver Opera.   I once again commend Goldcorp for being a corporate sponsor of the opera in Vancouver.  This is admirable and impressive.  (more…)

    A fine paper at the Banff, Alberta conference on Tailings & Mine Waste is that by John Sobokowicz and Norbert Morgenstern.  It is called “A Geotechnical Perspective on Oil Sands Tailings.”   In fact it would be a great paper if the presentation (soon to be available on the conference web site) had not focussed on the Alberta Energy and Resource Conservation Board (ERCB).  Recall the ERCB have concocted that utterly ridiculous requirement that oil sands tailings have a strength of 5 kPa one year after placement!

   The Alberta Resources Conservation Board (ERCB) has finally, formally issued oil sands tailings performance criteria and requirements. They are little changed from previous drafts.  They still focus on your ability to walk or drive out over the tailings soon after they have been placed. 

These regulations must mark a low point in the history of regulations that have high aims but get lost in trivia.  I know I am in a distinct minority in casting doubt on the wisdom of these regulations.  Everybody else I know approves of them and says they can achieve them.  I simply do not believe them.  (more…)
