One must admire NIOSH. The quality of their technical work is impressive and the clarity of their conference presentations outstanding. This afternoon in the CIM technical session Innovative Mining Technology, we enjoyed presentations from NIOSH staff on underhand cut-and-fill mining, new support concepts for hard rock mines, dust control for mines, and characterization of nonometer [...]

How does one make sence of an exhibition hall larger than a football field? I suppose you walk fast and find those companies that supply products and services you need. I started out doing this, until I came across an area marked out “South Africa.” Within a few minutes my American accent subsided and my [...]

The CIM is to be complimented on organizing an intelligent and informative plenary session to open this year’s conference in Montreal. Here is my first, brief report on this session—compiled from notes taken during the talks, and hence not always comprehensive or collated.

Iowa spring warmth made for a perfect weekend: I took the grandkids to the Belle Plaine park where we played on the weir as I tried to explain hydraulic jump. They thought I was crazy going on about energy changes in flowing water. So I lapsed into silence as they played on the swings and [...]

Participants in that meeting included EARTHWORKS, WWF, Partnership Africa Canada, Tiffany & Co. Foundation, The Council for Responsible Jewelry Practices (CRJP), the [...]

Most underground mines involve ventilation systems.  You need to push cool surface air down into those hot, deep workings to keep them cool.  The right temperature in underground mine workings is not only a matter of pleasant surroundings.  I recall reading that the accident rate jumps as the temperature increases: at about seventy degrees things [...]

No recommendations or endorsements implied in this posting.  But it is information that attracts my attention and it is information that may benefit a mine somewhere, so I pass it on.   Keep in mind I am a semi-retired professional engineer and produce this blog on the basis that I write what interests me, not what may be of [...]

I do not thinks there is anything wrong or inappropriate about the facts I cite in this article.  My Canadian friends bewail the fact that the United States is an imperial power, colonizing smaller nations and exploiting their resources.  They deny that Canada is as imperial a colonizer as any.  Consider Canadian ownership of United [...]
