My Challenge Here is a neat little challenge for my friends in the Sustainable Mining Business. This challenge is prompted by a fight I had yesterday over the Kemess North Mine, B.C. report as recently issued by a three person expert panel. I conclude that the panel rejects the mine for this basic reason: At [...]

Scoble’s Kemess Mine Report a “bad day for BC Mining?” or the “ARD Full-Employment Act?
Posted in About the news, Community relations, Hydrology and hydraulics, North America, Tailings on September 19, 2007 | Leave a Comment »
Last night I had supper with some senior folk in the BC mining industry. Their unequivocal opinion was that Scoble’s Kemess report constitutes a “bad day” for BC mining. When I explained that, in my opinion, the basis of the decisions was that ten years of mining income could not offset thousands of years of [...]

GoldSim and Marillana mine modeling: complex but satisfying
Posted in About the news, Australia and New Zealand, Hydrology and hydraulics, Open Pit, Reclamation on August 22, 2007 | Leave a Comment »
A webinar is when you log your computer into another website and make a phone call to a conference call. Then the webinar presenter talks via phone and shows figures on your computer’s screen. Much easier than fighting security at the airport to get to a strange city for a conference. But now I have [...]
GoldSim, mining, and personal prejudices re water and the environment
Posted in About the news, Hydrology and hydraulics on August 15, 2007 | Leave a Comment »
The issue of water resources is looming larger and larger in mining. Last week I read that some diamond mines in Botswana are mining groundwater faster than they are mining diamonds–they are predicting they will deplete local groundwater resources by 2012. They are looking for non-water-using ways to get the diamonds. My liberal friends deplore [...]
Ok Tedi get overwhelming local support: too good to be true?
Posted in About the news, Asia, Hydrology and hydraulics, Tailings on August 1, 2007 | 2 Comments »
Ok Tedi Mining is a big company. They get a lot of space in Wikipedia. It has had a checkered history. In spite of trying to practice sustainable devleopment. And one must empathise with the fact that the area’s high earthquake potential makes a tailings dam unsafe. Here are two documents that present somewhat different [...]
Cameco gets the groundwater story wrong again: uranium hexafluoride in the soil puts 420 out of work
Posted in About the news, Hydrology and hydraulics, Investing & Finance, North America, Uranium on July 24, 2007 | Leave a Comment »
I spent many years wondering around the American Southwest, poking around old uranium mines and mills. I worked around the old uranium production plants of Fernald and Weldon Springs. At these plants and at these old mills and mines, the soil was often heavily contaminated by uranium and its daughter products. Afterall the bombs were [...]
Riprap design procedures manual
Posted in About the news, Hydrology and hydraulics on June 2, 2007 | Leave a Comment »
Many a mine needs to control erosion in the surface water channels. If the mine is blessed with an abundance of good quality rock, riprap may be the most economic approach to limiting erosion. The best manual freely available on the web, in my opinion, is the California Bank and Shore Rock Slope Protection Design [...]
Mine surface water management: some free books chock full of information and practical procedures
Posted in About the news, Hydrology and hydraulics on May 30, 2007 | Leave a Comment »
These manuals, that are available for free download off the internet, have nothing to do with mining. Yet I submit they may constitute a valuable resourse for the new mines proposed in proximity to the cities for which these manuals are written. I make this submission on the basis that prudent policy dictates that every [...]
Computer models for mine surface water evaluation and design
Posted in About the news, Hydrology and hydraulics on May 29, 2007 | Leave a Comment »
Here is some practical advice I cull from Hydrology and Floodplain Analysis (1988) by Philip B. Bendient and Wayne C. Huber. They recommend the following steps in using models to simulate and analyze surface water management problems:
