A massive slope failure has occurred at the open pit of the Bingham Canyon Mine in Utah. Here is a link to a magnificent collection of photographs of the failure, which appears to have taken out part of a building, access roads, and filled the bottom of the pit with slide material. Nobody was hurt: the mine had been monitoring movement and when deformation increased from 1 mm a day to 5 mms day they pulled out all workers. A fine testament to the engineers who study rock and soil slope stability in the open pit mine context. (more…)

This is a story of a time before computers; before groundwater conceptual models, numerical models, baseline models, and predictive models; before groundwater model calibration, verification, or sensitivity analysis. This is a story of a time when there was no such thing as a professional geohydrologist, hydrogeologists, or groundwater modeller. (more…)
Engineering and Mining Journal (E&MJ) is published by Mining-Media. It arrives by no action on my part on my desk. There it joins the pile of magazines on mining that fall like leaves in autumn. Being a magazine junkie, I flip through them all. I avoid the articles on new trucks–those articles are surely planted by the manufacturers as disguised adverts. Add to that the article on new filtration equipment, new drills, and conferences in far places. (more…)
With the weekend about to begin here are links to two extremes of Canadian Mining:
- NWCC School of Exploration & Mining which surely represents the best and most positive aspects of Canadian mining
- Global day of Action Against Open Pit Mining which would be sad and infuriating if it were not so funny.
I leave you to formulate your own opinions. Enjoy the weekend.
Just received is the 2008 Survey Results U.S. Coal Mine Salaries, Wages and Benefits from CostMine. There is an enormous amount of data in this new survey. Here is my personal summary and perspective of some of the information on wages…..in future postings I will write about salaries and executive compensation.
