Today we completed a three-day EduMine webcast on  Mine Water Management.  Some thirty people from all over the world joined in.  Maybe you can join us next time we do this.  But for now, here are a few ideas on research opportunities in mine water management that came up during discussions.

Risk Assessment in Mine Water Management.  There were a few papers at the Tailings and Mine Waste Conference recently on risk assessment for tailings facility management.  I am not aware of any substantial work on the issue of risk assessment in mine water management in the broader context. Much has and can be done with GoldSim, but I know there is a need for fundamental research on this issue.  For example the recently issued Canadian Dam Association Guidelines on Mining Dams (aka Tailings Facilities) recommends design flood recurrence intervals based on the tailings facility hazard ranking.  Neat but without much justification or substantiation.

Acidic Tailings Polymer Amendment.   Polymer amendment of oil sands is successful.  But can this approach be used to limit acid production by tailings?  I have no idea and am not aware of any work in this regard.

Wetland Efficacy.   There is much written and much has been done on this topic.  I suspect, however, that there is much more to be done in the context of mining applications.

Perpetual Mine Water Treatment Cost Estimating.  In my view this is still one of the most difficult issues in mine water management.  It is being done all the time, yet it is still an art, not a science.  We need the deep financial types to tackle this one.

Dealing with Karst at Mine Sites.  There is a rich source of case histories on this issue in South Africa.  Most are tales of woe.  One way to do it is to put you structure that is underlain by karst geology on a foundation of cemented soil and rock—and preferable include copious geogrids in the foundation so that if the sinkhole develops, the foundation bridges the hole and the structure remain intact or at least does not fail rapidly and kill people.

Deep Ocean Disposal.  I have previously noted on this blog that the Chilean mining industry is looking into this practice in great detail.  Surely an examination in concert with Chile by other ocean-bordered countries would be a fascinating research topic for an aspiring young student.

I am sure there are many other interesting related research topics.  Please note your ideas as a comment.

Today I received the followings announcement by email.  I cannot find the original on the website of the BC Ministry of Energy and Mines (MEM).  Maybe they have not gotten down to posting it yet.  The announcement, in short, is that MEM has awarded Klohn Crippen Berger (KCB) a $1.5 million to help MEM evaluate the cause of the Mt Polley failure–more specifically to provide advice in conducting the “forensic investigation” into the breach.

Procopius wrote the most startling revelation of official incompetence and veniality. He wrote venerable histories about Belisariaus.   But he also wrote about the scandals of Justinian’s court.  Here is what one source says: (more…)

Today was a typical day in the life of a mining consultant.  One report was issued; one project put on hold; one request for proposals received; and a long discussion on how to deal with an obdurate client. (more…)

I was always healthy until I visited the doctor for a checkup.  Then they found all sorts of things wrong with me:  internal components not working; high levels of this and that and consequential concerns; indications of too much drink and smoking; blood pressure where it should not be;  weight too high; and so on.  Although I did loose some fifteen lbs on my recent trip to Peru and Chile. Maybe not enough alcohol,  lots of walking, and all that terrible Peruvian food.  How can you like raw fish in vinegar; black potatoes in squid ink; or slimy muscles in red pepper?  I cannot and probably ate too little.

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…)
